Slope stability analysis is a critical component of geotechnical engineering, with its implications reaching far and wide, from infrastructure development to environmental management. This study delves into the innovative Stress Deviator Increasing Method (SDIM) and its implications for slope analysis, focusing on the interaction of various components in this intricate process. This study acknowledges the evolution of slope stability analysis, transitioning from traditional methods such as the Limit Equilibrium Method (LEM) to modern approaches, and introduces SDIM as a promising alternative. Bouzid's SDIM combines the Finite Element Method (FEM) with Mohr's circles to offer a comprehensive understanding of slope behavior, particularly under complex stress conditions. The study meticulously examines SDIM's application through the S4DINA (soil stability study by Stress Deviator Increasing using Numerical Analysis) program, highlighting parameter sensitivity and the significance of considering specific conditions. The results underscore the sensitivity of SDIM to certain parameters, including the associated flow rule, finite element number, and embankment with or without foundations. Careful application of SDIM enhances the accuracy of slope stability assessments, allowing for more reliable results. This study represents a significant step in the field of geotechnical engineering, offering a dynamic and comprehensive approach that can address a wide range of scenarios and enhance the reliability of slope stability assessments.
