The elastoplastic Clay and Sand Model (CASM) extended to unsaturated conditions, formulated in terms of Bishop's stress and suction, has been implemented in an MPM‐based computational tool, in which gas density and pressure is assumed constant. The implementation of infiltration and seepage boundary conditions, required for wetting problems, are discussed and validated. A centrifuge experiment involving the construction, wetting, failure and post‐failure of a slope is interpreted and reproduced by the MPM‐based tool. Centrifuge data captured by video images, first analysed by particle image velocity (PIV) and then improved by the PIV‐numerical particle (NP) procedure, provides the motion and deformation of the entire experiment and is compared with calculations. The measured response of a 1D column of the model slope during the first stages of the test provided a first approximation of the constitutive parameters. The finally adopted set of model parameters led to a proper simulation of the entire response of the slope during wetting pre‐ and post‐failure stage.","PeriodicalId":13786,"journal":{"name":"International Journal for Numerical and Analytical Methods in Geomechanics","volume":"95 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The behaviour of these soils has been investigated extensively over compression triaxial paths, and models are available to successfully reproduce available experimental observations. However, open questions remain about the response over stress paths other than compression. In this study, an organic diatomaceous clay from the Netherlands was subjected to an extensive experimental programme, which included monotonic and non‐monotonic axis‐symmetric stress paths in both compression and extension. The comprehensive study introduces a new dataset to support the development and calibration of constitutive approaches. The collected experimental data revealed some limitations in current elastic–plastic models, which were addressed by introducing greater flexibility in the shape of the yield function and enhancing previous rotational hardening rules. The new model, named JMC‐clay, is assessed and validated over a variety of stress paths. The comparison between experimental data and numerical simulations demonstrates the ability of the model to accurately describe the pre‐failure behaviour. The findings emphasise that the model performance is particularly sensitive to elastic–plastic compressibility more than any other parameter. It is suggested that the true bottleneck in the practical implementation of this class of anisotropic formulations is their accurate initialisation, rather than calibration.","PeriodicalId":13786,"journal":{"name":"International Journal for Numerical and Analytical Methods in Geomechanics","volume":"40 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The procedure uses strain‐compatible shear moduli from one‐dimensional wave propagation analysis to calculate permanent deformations in the stream and dam‐axis directions using continuum‐mechanics‐based procedure. The continuum analysis results are used to identify regions of tensile stresses where cracks are likely to occur due to the seismic event. Validity of the procedure is checked by comparing results of computed deformations and tension zones with measured post‐seismic deformations and crack locations on two well‐instrumented earth dams. The computed deformations and tension zone locations are also compared with the results obtained by two‐ and three‐dimensional continuum‐based numerical analyses of the same dams by others.

However, most existing studies rely on one‐ or two‐dimensional simplifications, limiting their capacity to capture three‐dimensional stress–transport interactions. This study presents a fully three‐dimensional framework that integrates Biot's consolidation theory with the advection–diffusion equation. The model investigates solute transport under non‐uniform loading conditions—including segmented and centre‐decay schemes—and evaluates pollution scenarios involving static, temporally staggered, spatially expanding and stochastic point sources. Results show that non‐uniform loads significantly reshape pore pressure and deformation fields, which jointly govern solute redistribution. Segmented loading creates localized high‐pressure zones, intensifying solute accumulation, while centre‐decay loads promote broader dispersion through persistent transition‐zone gradients. Temporally dynamic sources lead to sequential redistribution patterns, whereas stochastic sources introduce concentration variability and overlapping hotspots. The proposed framework captures complex solute migration behaviours arising from coupled deformation and loading heterogeneity. It offers a versatile tool for analysing real‐world subsurface contamination and contributes to a better understanding of consolidation‐driven transport processes.","PeriodicalId":13786,"journal":{"name":"International Journal for Numerical and Analytical Methods in Geomechanics","volume":"51 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145127782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, studying the consolidation and creep behavior of saturated media under thermo‐mechanical coupling loads is of great significance for the development of energy geotechnical engineering. This study established the governing equations for multilayered transversely isotropic (TI) thermo‐viscoelastic saturated media based on the fractional Merchant model and obtained the solution to the governing equations using the Laplace–Hankel integral transform and an extended, precise integration method. Through numerical examples, the correctness of the theory and program in this paper is verified, and it is found that the transverse isotropy of the media has a significant impact on the time‐varying curves of displacement and pore pressure. Besides, as the fractional order increases, the consolidation and creep processes will be completed faster.

However, accurately predicting the cutting forces of disc cutters remains a significant challenge. To address this issue, a Support Vector Regression (SVR) model was introduced in this study to predict the normal force (FN) and rolling force (FR) based on an established dataset. To improve prediction accuracy, the SVR model's hyperparameters were optimized using three nature‐inspired algorithms: Whale Optimization Algorithm (WOA), Particle Swarm Optimization (PSO), and Crayfish Optimization Algorithm (COA). Performance evaluations using R<jats:sup>2</jats:sup>, VAF, NES, RMSE, and MAE demonstrated that the proposed hybrid models (WOA‐SVR, COA‐SVR, and PSO‐SVR) significantly outperformed traditional empirical and semi‐theoretical models, such as the Colorado School of Mines (CSM) model. Among these, the PSO‐SVR model yielded the best results (FN prediction: 0.9657, 96.5241%, 0.9652, 15.0258, 11.6712; FR prediction: 0.9691, 95.3219%, 0.9517, 2.3272, 1.6531). Furthermore, SHapley Additive exPlanations (SHAP) and Local Interpretable Model‐agnostic Explanations (LIME) were employed to enhance model interpretability. The analysis revealed that uniaxial compressive strength (UCS), cutter penetration depth (P), and disc cutter spacing (S) play a pivotal role in the accurate prediction of FN and FR. Additionally, a MATLAB‐based visual interface was developed to provide practical technical support for optimizing real‐world TBM tunneling performance.","PeriodicalId":13786,"journal":{"name":"International Journal for Numerical and Analytical Methods in Geomechanics","volume":"35 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145089307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An innovative two‐dimensional analytical model is developed to examine volatile organic compounds (VOCs) migration via a four‐layered soil cover made up of a gas recovery layer, compacted clay liner (CCL) layer, geomembrane (GMB), and protective layer. The effects of source concentration distribution, LFG collection system, saturation degree, contaminant degradation rate, and GMB on cover system performance were evaluated. For a significantly more tightly clustered source concentration, 1D models tend to produce more conservative results in contrast to the 2D models based on the analysis of nonuniform contamination source distribution. Results show that increasing saturation degree (<jats:italic>S<jats:sub>r</jats:sub></jats:italic>) and degradation rate lead to lower steady‐state surface flux. VOCs migration in the cover system is more sensitive to <jats:italic>S<jats:sub>r</jats:sub></jats:italic> variation in the CCL and gas recovery layer than that in the protective layer.

An intact GMB layer and the gas collection flow rate of over 6 m<jats:sup>3</jats:sup>/s are required for the cover system to achieve a 70% LFG collection efficiency and satisfy the surface flux tolerance value.

This study investigates the effect of time step refinement on numerical solutions for a vertical infiltration 1D test in a vertical column.

Then, the numerical and mathematical convergences of the numerical solutions were studied versus the time step, Δ<jats:italic>t</jats:italic>. The study provided results for hydraulic head, unsaturated hydraulic conductivity, volumetric water content, and vertical water velocity versus elevation, elapsed time <jats:italic>t</jats:italic>, and Δ<jats:italic>t</jats:italic>. Asymptotic behavior was obtained for all unknowns when Δ<jats:italic>t</jats:italic> → 0.

This study presents a comprehensive comparison of the soil arching effect under five initial states and three burial depths subjected to seismic shaking, utilizing numerical trapdoor tests performed with the discrete element method. The results showed that following the multi‐stage fluctuations caused by seismic wave input, the ultimate arching ratio increased, signaling a weakening of the soil arching effect. The difference in the soil arching ratio gradually decreased as the trapdoor displacement increased. For the same burial depth, the variation in the soil arching ratio exhibited a quadratic relationship with the normalized trapdoor displacement. As trapdoor displacement increased, the stress ratio changes oscillated in response to seismic waves, with direction inversely related to the waveforms. The areas most affected by seismic shaking were near the trapdoor. An increase in normalized trapdoor displacement corresponds to a decrease in the ultimate coordination number, which follows an inverse relationship that can be described by a linear function. After seismic action, force chains above the trapdoor strengthened, while their intensity decreased in the stable region. Increased burial depth amplified seismic‐induced force chains within the trapdoor width. The major axis orientation and shape in the contact rose diagrams remained unchanged, though horizontal contacts increased, with this increase becoming more pronounced as trapdoor displacement grew.","PeriodicalId":13786,"journal":{"name":"International Journal for Numerical and Analytical Methods in Geomechanics","volume":"49 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145077318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most existing models pay limited attention to the influence of loading frequency, particularly in scenarios involving a large number of cycles. To address this gap, this paper develops a three‐surface elastic‐viscoplastic cyclic model for clays. The proposed model incorporates several notable features: (1) a unified framework that integrates bounding surface theory and overstress theory through the introduction of a dynamic bounding surface, enabling the model to capture both viscous and cyclic behaviors; (2) a viscoplastic modulus associated with the dynamic loading surface, which incorporates the effect of accumulated viscoplastic strain, allowing for flexible control of axial strain and pore water pressure development under cyclic loading paths; and (3) consideration of anisotropy in both elastic and viscoplastic responses, together with a non‐associative flow rule, which improves the model's ability to simulate complex cyclic behavior. The model's performance is evaluated by comparing its predictions with results from four series of cyclic undrained triaxial tests, which vary in the number of cycles, cyclic stress amplitudes, loading frequencies, and OCRs. To maintain simplicity, the proposed formulation does not include destructuration, kinematic hardening, or mapping rules with relocatable projection centers. These features can be incorporated later if required by specific applications.","PeriodicalId":13786,"journal":{"name":"International Journal for Numerical and Analytical Methods in Geomechanics","volume":"3 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145072038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
