This study challenges that notion by developing a universal empirical model that captures its significant stress-dependency from initial loading to failure. The model was rigorously calibrated using 42 uniaxial compressive tests on granite and successfully generalized to limestone, marl, sandstone, and saltstone, representing a wide spectrum of mechanical behaviors from brittle to ductile. Its predictive accuracy was quantified using root mean square error (RMSE), mean absolute error (MAE), and mean absolute percentage error (MAPE). The model demonstrated high fidelity, particularly at the critical crack initiation stage (sigma/sigma c = 0.5), where errors were minimized. Across all five rock types and three calculation methods (secant, average, tangent), the MAPE ranged from 1.4% to 3.7%, RMSE from 0.007 to 0.012, and MAE from 0.005 to 0.010. Performance was superior for ductile rocks like marl (MAPE approximate to 1.9%) and saltstone (MAPE approximate to 1.4%) due to their homogeneous deformation, while effectively capturing the more complex, crack-dominated response of granite and sandstone. The research conclusively demonstrates that Poisson's ratio is not a fixed material property but a dynamically evolving parameter. This work provides a practical and robust framework that moves beyond the assumption of a constant Poisson's ratio, offering a significant improvement for accurate deformation analysis in numerical modeling, underground excavation design, and reservoir geomechanics. true true NATIONAL 2025 true true true false true false NONE 2026-06-01 false 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 7 7 D1 false false false false 2025-11-24T13:32:35.833+0000 Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 2 13 1 2 0 true 10063514 Language 10002 /api/language/10002 Angol Angol English true 2 true PersonAuthorship 128667095 /api/authorship/128667095 Narimani, Samad ✉ [Narimani Ghourtlar, Samad (Geotechnics, Geol...), szerző] Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 1 0.5 true false true Author 10081821 /api/author/10081821 Narimani Ghourtlar Samad (Geotechnics, Geology, Rock Mechanics, Tunneling, Geomechanics, Machine Learning) Narimani Ghourtlar Samad true true Narimani Samad true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PersonAuthorship 128667096 /api/authorship/128667096 Vásárhelyi, Balázs [Vásárhelyi, Balázs (Kőzetmechanika), szerző] Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 2 0.5 false true false Author 10002250 /api/author/10002250 Vásárhelyi Balázs (Kőzetmechanika) Vásárhelyi Balázs true 10002250 true Vásárhelyi Balázs true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PublicationIdentifier 30219399 /api/publicationidentifier/30219399 DOI: 10.1002/nag.70146 PlainSource 6 /api/publicationsource/6 DOI PublicationSourceType 10001 /api/publicationsourcetype/10001 DOI true true true DOI DOI https://doi.org/@@@ true true 6 true IDENTICAL 10.1002/nag.70146 https://doi.org/10.1002/nag.70146 false true PublicationIdentifier 30219400 /api/publicationidentifier/30219400 WoS: 001613735200001 PlainSource 1 /api/publicationsource/1 WoS PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true IDENTICAL 001613735200001 https://www.webofscience.com/wos/woscc/full-record/001613735200001 false true PublicationIdentifier 30219428 /api/publicationidentifier/30219428 Scopus: 105021527651 PlainSource 3 /api/publicationsource/3 Scopus PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true IDENTICAL 105021527651 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-105021527651 false true PublicationIdentifier 30203571 /api/publicationidentifier/30203571 Egyéb URL: https://onlinelibrary.wiley.com/doi/10.1002/nag.70146 PlainSource 40 /api/publicationsource/40 Egyéb URL PublicationSourceType 10006 /api/publicationsourcetype/10006 Link true true true Egyéb URL Other URL @@@ true true 40 true https://onlinelibrary.wiley.com/doi/10.1002/nag.70146 https://onlinelibrary.wiley.com/doi/10.1002/nag.70146 false true Keyword 1538 /api/keyword/1538 STRESS true 1538 true Keyword 7239 /api/keyword/7239 FRACTURE true 7239 true Keyword 12051 /api/keyword/12051 VALUES true 12051 true Keyword 13403 /api/keyword/13403 PROPAGATION true 13403 true Keyword 1000485 /api/keyword/1000485 INITIATION true 1000485 true Keyword 1020712 /api/keyword/1020712 THRESHOLDS true 1020712 true Keyword 1098811 /api/keyword/1098811 Empirical model true 1098811 true Keyword 1493583 /api/keyword/1493583 Materials Science, Multidisciplinary true true Keyword 1643416 /api/keyword/1643416 Poisson's ratio true true Keyword 1707725 /api/keyword/1707725 Engineering, Geological true true Keyword 1887138 /api/keyword/1887138 crack initiation stress true true Keyword 3937096 /api/keyword/3937096 crack damage stress true true SjrRating 11688122 /api/sjrrating/11688122 sjr:D1 (2026) Scopus - Computational Mechanics INTERNATIONAL JOURNAL FOR NUMERICAL AND ANALYTICAL METHODS IN GEOMECHANICS 0363-9061 1096-9853 8 0.1 journal RatingType 10002 /api/ratingtype/10002 sjr sjr true true ClassificationExternal 2206 /api/classificationexternal/2206 Scopus - Computational Mechanics true 2206 true D1 FROM_LAST_YEAR true true /api/publication/36454998 Narimani Samad et al.

The database includes essential mechanical parameters, such as crack initiation stress and crack damage stress, as outputs, and unconfined compressive stress, Young's modulus, and Poisson's ratio as inputs. The study employs multivariate regression analysis (MRA), Decision tree (DT), and artificial neural network (ANN) techniques to analyze the data. To assess and compare the performance of these models, various metrics are used, including root-mean-square error (RMSE), mean absolute error (MAE), coefficient of determination (R²), mean absolute percent error (MAPE) and the a20-index. The findings reveal that the ANN method surpasses MRA-based and decision tree regression-based approaches in accurately predicting the output parameters. The ANN model demonstrates outstanding predictive performance for σci, achieving an R²=0.934, RMSE=5.965, MAE=4.79, MAPE=5.3% and VAF=93.34%. Similarly, the model excels in predicting σcd with an R²=0.985, RMSE=4.676, MAE=3.785, MAPE=2.3%, VAF=98.4%, Additionally, sensitivity analysis identifies unconfined Compressive stress (UCS) as the most critical factor in predicting crack initiation stress (σci) and crack damage stress (σcd). The findings suggest that the ANN model is more effective in predicting σci and σcd of rocks compared to other methods. true false 2025 true true true true true false NONE 2026-06-01 false 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2 2 false false false false 2025-09-25T05:06:57.985+0000 Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 2 13 1 3 0 true 1792 true 10002 English /api/language/10002 Angol Language Angol true 2 false true 10734 true 10037 /api/country/10037 Country Norvégia true 2149062 /api/city/10734 City Oslo, Norvégia true 1308895 true 29667129 /api/publicationidentifier/29667129 https://www.worldcat.org/search?q=isbn%3A9788282080798 9788282080798 PublicationIdentifier ISBN: 9788282080798 true 122 ISBN https://www.worldcat.org/search?q=isbn%3A@@@ /api/publicationsource/122 ISBN PlainSource ISBN true true 10002 /api/publicationsourcetype/10002 PublicationSourceType Egyéb true false 122 true false true 31950087 /api/publicationidentifier/31950087 https://hdl.handle.net/11250/3574972 https://hdl.handle.net/11250/3574972 PublicationIdentifier Repozitóriumban: https://hdl.handle.net/11250/3574972 true 142 @@@ /api/publicationsource/142 Repozitóriumban PlainSource Repozitóriumban true true 10006 /api/publicationsourcetype/10006 PublicationSourceType Link true true 142 true false true 29667136 /api/publicationidentifier/29667136 https://eurock2025.com/proceedings https://eurock2025.com/proceedings PublicationIdentifier Teljes dokumentum: https://eurock2025.com/proceedings true 39 Full text @@@ /api/publicationsource/39 Teljes dokumentum PlainSource Teljes dokumentum true true 10006 /api/publicationsourcetype/10006 PublicationSourceType Link true true 39 true false /api/publication/36272080 Kristin Hilde Holmøy.

However, according to the suggestion of the International Society for Rock Mechanics, Poisson’s ratio can be determined using three alternative methods: the secant, average and tangent. Applying these methods causes discrepancies in the results; according to our experiences, the differences can be threefold or more. This paper aims to study the process of changes of Poisson’s ratio for intact rock during loading from micro-crack initiation to failure stage. The objective of this theoretical investigation is to establish a straightforward mathematical formulation between σ/σ c and intact rock’s Poisson’s ratio value. To outline these changes forty two granite rocks were investigated from Bátaapáti radioactive waste repository (Hungary) and the calculation was performed by using the new formula from the beginning of loading till failure stage at UCS test. In the laboratory test program, Poisson’s ratio derived from standard tests varies with momentary stress; it steadily increases as stress rises until reaching the stress level causing unstable crack propagation. Additionally, the Poisson’s rate follows a linear increase with stress, up to the point of unstable crack propagation stress. The research demonstrated that the proposed equations provide competent values for the root mean squared error value (ranging from 0 to 0.04), the mean absolute percentage error (ranging from 0.6% to 18%) and the mean absolute error (ranging from 0 to 0.04). Contrary to previous ideas, our results suggest that the Poisson’s ratio is not a constant for rigid rocks. true 2025 true true true false true false GOLD 2026-06-01 true https://doi.org/10.1038/s41598-024-75892-2 4 0 4 3 1 4 4 2 3 3 3 2 2 3 1 0 4 3 4 3 0 10 10 Q1 A nemzetközi false false false false 2025-05-16T07:41:26.307+0000 Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 2 13 1 3 0 true 10063514 Language 10002 /api/language/10002 Angol Angol English true 2 true PersonAuthorship 126412737 /api/authorship/126412737 Narimani, Samad ✉ [Narimani Ghourtlar, Samad (Geotechnics, Geol...), szerző] Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 1 0.333 true false true Author 10081821 /api/author/10081821 Narimani Ghourtlar Samad (Geotechnics, Geology, Rock Mechanics, Tunneling, Geomechanics, Machine Learning) Narimani Ghourtlar Samad true true Narimani Samad true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PersonAuthorship 126412738 /api/authorship/126412738 Kovács, László 2 0.33333334 false false false Kovács László true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PersonAuthorship 126412739 /api/authorship/126412739 Vásárhelyi, Balázs [Vásárhelyi, Balázs (Kőzetmechanika), szerző] Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 3 0.333 false true false Author 10002250 /api/author/10002250 Vásárhelyi Balázs (Kőzetmechanika) Vásárhelyi Balázs true 10002250 true Vásárhelyi Balázs true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PublicationIdentifier 29328582 /api/publicationidentifier/29328582 DOI: 10.1038/s41598-024-75892-2 PlainSource 6 /api/publicationsource/6 DOI PublicationSourceType 10001 /api/publicationsourcetype/10001 DOI true true true DOI DOI https://doi.org/@@@ true true 6 true GOLD true IDENTICAL 10.1038/s41598-024-75892-2 https://doi.org/10.1038/s41598-024-75892-2 false true PublicationIdentifier 29394917 /api/publicationidentifier/29394917 WoS: 001485522500004 PlainSource 1 /api/publicationsource/1 WoS PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true IDENTICAL 001485522500004 https://www.webofscience.com/wos/woscc/full-record/001485522500004 false true PublicationIdentifier 29381960 /api/publicationidentifier/29381960 Scopus: 105004443458 PlainSource 3 /api/publicationsource/3 Scopus PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true IDENTICAL 105004443458 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-105004443458 false true PublicationIdentifier 29394916 /api/publicationidentifier/29394916 PubMed: 40341380 PlainSource 17 /api/publicationsource/17 PubMed PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true PubMed PubMed http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=@@@&dopt=Abstract true true 17 true IDENTICAL 40341380 http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=40341380&dopt=Abstract false true PublicationIdentifier 29328583 /api/publicationidentifier/29328583 Egyéb URL: https://www.nature.com/articles/s41598-024-75892-2 PlainSource 40 /api/publicationsource/40 Egyéb URL PublicationSourceType 10006 /api/publicationsourcetype/10006 Link true true true Egyéb URL Other URL @@@ true true 40 true IDENTICAL https://www.nature.com/articles/s41598-024-75892-2 https://www.nature.com/articles/s41598-024-75892-2 false true MtaRating 519359 /api/mtarating/519359 IX.

Researchers frequently estimate these values indirectly because it is not always feasible to get high-quality core samples. Four machine learning models including multiple linear regression (MLR), multiple nonlinear regression (MNLR), artificial neural networks (ANN) and Adaptive Neuro-Fuzzy Inference System (ANFIS) were introduced and employed to examine the prediction of UCS and E in 221 granitic rock samples from Bataapáti nuclear reservoir in Hungary. The variables to calculate UCS and E are: density, P-wave velocity, shear strength and Brazilian tensile strength. The study compared the performance of the proposed machine learning models and found that the ANFIS model had obtained the most satisfactory prediction accuracy. Based on the sensitive analysis, the BTS is the most important variable for predicting UCS and Vp for E. Six popular performance indices, including the root-mean-square error (RMSE), mean absolute error (MAE), the coefficient of determination (R2), mean absolute percent error (MAPE), variance accounts for (VAF) and a20-index were adopted to evaluate all models. The ANFIS model demonstrates outstanding predictive performance for UCS, achieving an R²=0.99, RMSE = 2.445, MAE = 1.489, MAPE = 1.3%, VAF = 99.16%, and an a20-index of 1 for the training datasets. For the testing datasets, it attains an R²=0.97, RMSE = 5.544, MAE = 3.502, MAPE = 3.1%, VAF = 96.43%, and an a20-index of 1. Similarly, the model excels in predicting E with an R²=0.93, RMSE = 3.914, MAE = 2.91, MAPE = 5.2%, VAF = 92.23%, and an a20-index of 1 for training datasets, and an R²=0.92, RMSE = 3.195, MAE = 2.613, MAPE = 4.4%, VAF = 92.22%, and an a20-index of 1 for testing datasets. Also, a sequence of Taylor diagrams was generated to assess the performance of the models. The findings suggest that the ANFIS model is more effective in predicting UCS and E of rocks compared to other methods. However, its application should be approached cautiously, especially at the initial design phase, and limited to specific rock types. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024. true true 2025 true true true false true false GOLD 2026-08-05 true https://doi.org/10.1007/s12145-024-01653-4 11 0 11 10 1 11 10 9 5 9 9 9 9 10 1 0 11 10 11 10 0 7 7 Q1 false false false false 2025-04-08T07:25:04.668+0000 Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 2 13 1 2 0 true 10063514 Language 10002 /api/language/10002 Angol Angol English true 2 true PersonAuthorship 122614608 /api/authorship/122614608 Narimani, Samad ✉ [Narimani Ghourtlar, Samad (Geotechnics, Geol...), szerző] Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 1 0.5 true false true Author 10081821 /api/author/10081821 Narimani Ghourtlar Samad (Geotechnics, Geology, Rock Mechanics, Tunneling, Geomechanics, Machine Learning) Narimani Ghourtlar Samad true true Narimani Samad true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PersonAuthorship 122614609 /api/authorship/122614609 Vásárhelyi, Balázs [Vásárhelyi, Balázs (Kőzetmechanika), szerző] Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 2 0.5 false true false Author 10002250 /api/author/10002250 Vásárhelyi Balázs (Kőzetmechanika) Vásárhelyi Balázs true 10002250 true Vásárhelyi Balázs true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PublicationIdentifier 28165918 /api/publicationidentifier/28165918 DOI: 10.1007/s12145-024-01653-4 PlainSource 6 /api/publicationsource/6 DOI PublicationSourceType 10001 /api/publicationsourcetype/10001 DOI true true true DOI DOI https://doi.org/@@@ true true 6 true GOLD true IDENTICAL 10.1007/s12145-024-01653-4 https://doi.org/10.1007/s12145-024-01653-4 false true PublicationIdentifier 28165919 /api/publicationidentifier/28165919 WoS: 001381247700004 PlainSource 1 /api/publicationsource/1 WoS PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true IDENTICAL 001381247700004 https://www.webofscience.com/wos/woscc/full-record/001381247700004 false true PublicationIdentifier 28165917 /api/publicationidentifier/28165917 Scopus: 85212765311 PlainSource 3 /api/publicationsource/3 Scopus PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true IDENTICAL 85212765311 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-85212765311 false true PublicationIdentifier 28124318 /api/publicationidentifier/28124318 Egyéb URL: https://link.springer.com/10.1007/s12145-024-01653-4 PlainSource 40 /api/publicationsource/40 Egyéb URL PublicationSourceType 10006 /api/publicationsourcetype/10006 Link true true true Egyéb URL Other URL @@@ true true 40 true IDENTICAL https://link.springer.com/10.1007/s12145-024-01653-4 https://link.springer.com/10.1007/s12145-024-01653-4 false true Keyword 3374 /api/keyword/3374 Hungary true 3374 true Keyword 4002 /api/keyword/4002 Regression Analysis true 4002 true Keyword 4425 /api/keyword/4425 Sensitivity analysis true 4425 true Keyword 12390 /api/keyword/12390 machine learning true 12390 true Keyword 1001459 /api/keyword/1001459 uniaxial compressive strength true 1001459 true Keyword 1004970 /api/keyword/1004970 Compressive Strength true 1004970 true Keyword 1022921 /api/keyword/1022921 Young's modulus true 1022921 true Keyword 1077839 /api/keyword/1077839 shear strength true 1077839 true Keyword 1160324 /api/keyword/1160324 P-wave true 1160324 true Keyword 1179069 /api/keyword/1179069 Machine learning methods true 1179069 true Keyword 1534996 /api/keyword/1534996 Multivariate regression analysis true true Keyword 1575464 /api/keyword/1575464 reservoir rock true true Keyword 3674162 /api/keyword/3674162 Intact granitic rock true true SjrRating 11573831 /api/sjrrating/11573831 sjr:Q1 (2025) Scopus - Earth and Planetary Sciences (miscellaneous) EARTH SCIENCE INFORMATICS 1865-0473 1865-0481 80 0.24 journal RatingType 10002 /api/ratingtype/10002 sjr sjr true true ClassificationExternal 1901 /api/classificationexternal/1901 Scopus - Earth and Planetary Sciences (miscellaneous) true 1901 true Q1 DIRECT true true /api/publication/35667976 Narimani Samad et al.

Poisson's ratio has not gotten the attention it merits compared to other essential mechanical characteristics of intact rock and rock mass. Limited relationships exist between rock mass classification systems (such as RMR, RMQR, Q, and GSI) and Poisson's ratio. This paper provides a comprehensive review of models proposed by various researchers for estimating Poisson's ratio for rock mass. The different methods are compared, and new general equations are derived. The results indicate that the Poisson's ratio value of rock mass is inversely proportional to its quality and strength and depends on the Poisson's ratio value of the intact rock. Specifically, a linear equation is obtained using the RMR or GSI system, showing that the Poisson's ratio increases as the quality and strength of the rock mass decrease. The Q system has a logarithmic link between the rock mass quality and Poisson's ratio. It should be noted that the derived equations are applicable only under the assumption of a homogeneous isotropic rock mass. 2023 false true true false true false GOLD 2026-06-01 true https://doi.org/10.3311/PPci.22689 23 0 22 18 4 23 22 19 18 20 20 16 16 19 4 0 23 19 22 18 0 14 14 Q2 A false false false false 2024-01-11T12:34:09.245+0000 Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 3 13 1 3 0 true 10063514 Language 10002 /api/language/10002 Angol Angol English true 2 true PersonAuthorship 111071476 /api/authorship/111071476 Narimani, Samad [Narimani Ghourtlar, Samad (Geotechnics, Geol...), szerző] Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 1 0.333 true false false Author 10081821 /api/author/10081821 Narimani Ghourtlar Samad (Geotechnics, Geology, Rock Mechanics, Tunneling, Geomechanics, Machine Learning) Narimani Ghourtlar Samad true true Narimani Samad true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PersonAuthorship 111071477 /api/authorship/111071477 Davarpanah, Seyed Motreza [Davarpanah, Seyed Morteza (építőmérnöki tudo...), szerző] Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 2 0.333 false false false Author 10061327 /api/author/10061327 Davarpanah Seyed Morteza (építőmérnöki tudományok) Davarpanah Seyed Morteza true 10061327 true Davarpanah Seyed Motreza true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PersonAuthorship 111071478 /api/authorship/111071478 Vasarhelyi, Balazs ✉ [Vásárhelyi, Balázs (Kőzetmechanika), szerző] Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 3 0.333 false true true Author 10002250 /api/author/10002250 Vásárhelyi Balázs (Kőzetmechanika) Vásárhelyi Balázs true 10002250 true Vasarhelyi Balazs true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PublicationIdentifier 24616650 /api/publicationidentifier/24616650 DOI: 10.3311/PPci.22689 PlainSource 6 /api/publicationsource/6 DOI PublicationSourceType 10001 /api/publicationsourcetype/10001 DOI true true true DOI DOI https://doi.org/@@@ true true 6 true GOLD true IDENTICAL 10.3311/PPci.22689 https://doi.org/10.3311/PPci.22689 false true PublicationIdentifier 24616651 /api/publicationidentifier/24616651 WoS: 001081930900001 PlainSource 1 /api/publicationsource/1 WoS PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true IDENTICAL 001081930900001 https://www.webofscience.com/wos/woscc/full-record/001081930900001 false true PublicationIdentifier 25365300 /api/publicationidentifier/25365300 Scopus: 85182602316 PlainSource 3 /api/publicationsource/3 Scopus PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true IDENTICAL 85182602316 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-85182602316 false true PublicationIdentifier 30204046 /api/publicationidentifier/30204046 Egyéb URL: https://pp.bme.hu/ci/article/view/22689 PlainSource 40 /api/publicationsource/40 Egyéb URL PublicationSourceType 10006 /api/publicationsourcetype/10006 Link true true true Egyéb URL Other URL @@@ true true 40 true IDENTICAL https://pp.bme.hu/ci/article/view/22689 https://pp.bme.hu/ci/article/view/22689 false true Keyword 1538 /api/keyword/1538 STRESS true 1538 true Keyword 7293 /api/keyword/7293 YOUNGS MODULUS true 7293 true Keyword 1003853 /api/keyword/1003853 strength true 1003853 true Keyword 1395783 /api/keyword/1395783 Rock mass classification true 1395783 true Keyword 1442935 /api/keyword/1442935 Rock mass true 1442935 true Keyword 1643416 /api/keyword/1643416 Poisson's ratio true true MtaRating 11435475 /api/mtarating/11435475 X.

This core logging procedure is the basic parameter in the most useful rock mass classification methods like Rock Mass Rate (RMR) and Rock Mass Quality (Q). It is also used to determine the Geological Strength Index (GSI), which has become widely used in the last 20 years. One of the basic problems of the RQD value is that it does not distinguish different rock cores longer than 10 cm (100% is obtained for one piece of 1 m length and 10 pieces of 10 cm length) and a uniform result is obtained for shorter units. In this paper, the so-called Integrated RQD (Int_RQD) factor is introduced to eliminate these problems and to provide a better description of fracture density in the core logging procedure. As it uses the original core logging procedure, historical RQD data can also be reevaluated. Considering that RQD is an input parameter for most rock engineering classifications, these systems such as GSI can be reviewed based on the new RQD definition proposed herein. true 2024 true true true false true false GOLD 2026-06-01 true https://doi.org/10.3390/geotechnics3040055 3 0 3 2 1 2 3 1 3 3 3 2 2 2 1 0 3 2 3 2 0 8 8 false false false false 2024-05-08T10:27:14.138+0000 Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 2 11 1 2 0 false 10063514 Language 10002 /api/language/10002 Angol Angol English true 2 true PersonAuthorship 114309455 /api/authorship/114309455 Somodi, Gábor [Somodi, Gábor (Geológia), szerző] Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 1 0.5 true false false Author 10086735 /api/author/10086735 Somodi Gábor (Geológia) Somodi Gábor true true Somodi Gábor true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PersonAuthorship 114309456 /api/authorship/114309456 Vásárhelyi, Balázs ✉ [Vásárhelyi, Balázs (Kőzetmechanika), szerző] Geotechnika és Mérnökgeológia Tanszék (BME / ÉMK) 2 0.5 false true true Author 10002250 /api/author/10002250 Vásárhelyi Balázs (Kőzetmechanika) Vásárhelyi Balázs true 10002250 true Vásárhelyi Balázs true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PublicationIdentifier 25446398 /api/publicationidentifier/25446398 DOI: 10.3390/geotechnics3040055 PlainSource 6 /api/publicationsource/6 DOI PublicationSourceType 10001 /api/publicationsourcetype/10001 DOI true true true DOI DOI https://doi.org/@@@ true true 6 true GOLD true IDENTICAL 10.3390/geotechnics3040055 https://doi.org/10.3390/geotechnics3040055 false true PublicationIdentifier 27306438 /api/publicationidentifier/27306438 WoS: 001282002500001 PlainSource 1 /api/publicationsource/1 WoS PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true IDENTICAL 001282002500001 https://www.webofscience.com/wos/woscc/full-record/001282002500001 false true PublicationIdentifier 28426860 /api/publicationidentifier/28426860 Scopus: 85199390768 PlainSource 3 /api/publicationsource/3 Scopus PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true IDENTICAL 85199390768 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-85199390768 false true PublicationIdentifier 25446399 /api/publicationidentifier/25446399 Egyéb URL: https://www.mdpi.com/2673-7094/3/4/55 PlainSource 40 /api/publicationsource/40 Egyéb URL PublicationSourceType 10006 /api/publicationsourcetype/10006 Link true true true Egyéb URL Other URL @@@ true true 40 true IDENTICAL https://www.mdpi.com/2673-7094/3/4/55 https://www.mdpi.com/2673-7094/3/4/55 false true Classification 10807 /api/classification/10807 Műszaki és technológiai tudományok true true /api/publication/34567022 Somodi Gábor et al.
