Reliability Analysis with Correlated Non-Gaussian Inputs of Unsaturated Soil Slopes for Surrogate-Enhanced MCS Using a Parallelized Morgenstern-Price Framework, FORM, and SORM Kenue Abdul Waris, B. Munwar Basha International Journal of Geomechanics, 2026 This study presents a parallelized framework for the grid-and-radius-based Morgenstern–Price method to enable an efficient reliability analysis of unsaturated finite soil slopes under correlated and non-Gaussian conditions. To address the limitations of deterministic techniques and the significant computational demands associated with traditional Monte Carlo simulation, the framework incorporates surrogate modeling approaches, namely polynomial chaos expansion–enhanced Monte Carlo simulation (PCE-MCS) and Kriging-based Monte Carlo simulation (K-MCS). This research conducts a comprehensive evaluation of these surrogate-assisted methods with the gradient-based approaches for estimating the probability of failure (pf) under correlated and non-Gaussian distributions. The surrogate models exhibit exceptional accuracy (R2 > 99.7%, mean absolute error <0.6%) and drastically reduce computational cost compared with traditional methods. Parametric and variability studies show that increasing the mean stability number (0.005–0.065) and friction angle (20°–30°) reduces the pf from 19.19% to 0.005% and 14.9% to 0.01%, respectively, while higher variability increases pf. Similarly, increasing the air-entry value reduces pf from 29.8% to 0.01%, whereas pf rises to 15.1% and 21.8% with increases in soil–water characteristic curve parameters nf (0.1–3.25) and mf (0.25–1.65). A detailed comparison against gradient-based techniques such as the first-order reliability method (FORM) and the second-order reliability method (SORM) underscores the superiority of surrogate-based approaches. For instance, the FORM shows errors up to 92.59%, while SORM errors reach 62.75%, particularly in highly nonlinear or variable scenarios. In contrast, PCE-MCS and K-MCS errors remain generally below 10%. Furthermore, reliability-based design contour charts are developed using K-MCS. These charts align with the USACE reliability classification, enabling rapid and reliable assessment of unsaturated slope stability without the need for large-scale simulations. Therefore, by effectively bridging traditional geotechnical engineering and advanced surrogate techniques, the proposed approach enhances practical decision-making in unsaturated slope design and supports the advancement of reliability-based design optimization in geotechnical practice.
Experimental Investigations of Narrow Backfill Retaining Walls under Translation Mode S. Danish Bashir, B. Munwar Basha, M. Roshan Khan International Journal of Geomechanics, 2025 Narrow backfill retaining walls (NBRWs) play a key role in stabilizing slopes in constrained environments such as mountainous regions and urban areas. This study investigates the behavior of NBRWs through large-scale experiments using a custom-built tank, examining aspect ratios (b/H) from 0.2 to 0.7 and relative densities of 70%, 75%, and 80%. The active earth thrust (Pa) value is experimentally determined to be 12% lower than Coulomb’s predictions for b/H = 0.2. Moreover, the decrease in active earth pressure at the base of the wall is more pronounced, with reductions of up to 42%, 26%, 21%, 16%, and 9% compared with Coulomb’s theory for b/H = 0.2, 0.3, 0.4, 0.5, and 0.6, respectively. The experimental values of active earth pressure (pa) align closely with Coulomb’s theory when b/H = 0.7. These results closely align with the multiwedge theory proposed in previous studies, showing slight differences, confirming the theory’s applicability to NBRWs. These findings highlight the importance of refined large-scale experimental models to improve predictions and ensure safer, more efficient designs for NBRWs in constrained environments.
Seismic Stability Evaluation of Landfill Veneer Cover Systems Using Modified Pseudo-Dynamic Method Soujanya Dabbiru, B. Munwar Basha Journal of Earthquake Engineering, 2025 This study evaluates the seismic stability of veneer cover systems, addressing the sliding failure (SF) and uplifted-floating failure (UF) caused by retained water. The modified pseudo-dynamic (MPD) method, considering hydrostatic, hydrodynamic, and seismic forces, is employed. Comparison of the results with the literature under the pseudo-static (PS) and pseudo-dynamic (PD) loading conditions highlight the precision of the MPD method. Consideration of the visco-elastic behavior and soil damping in the analysis enhances the accuracy of the MPD method. Design charts are proposed for the determination of the allowable thickness of cover soil, which is cost-effective, ensuring seismic safety against SF and UF modes.
