Reliability Analysis with Correlated Non-Gaussian Inputs of Unsaturated Soil Slopes for Surrogate-Enhanced MCS Using a Parallelized Morgenstern–Price Framework, FORM, and SORM

Abstract

Abstract 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 ... Practical Applications This study presents an efficient framework for assessing the reliability of unsaturated soil slopes, in which suction and soil–water interactions influence stability. By integrating surrogate models with Monte Carlo simulation (MCS)...
