Exploration of Methods for Slope Stability Analysis Influenced by Unsaturated Soil

This study will lead to the analysis of unsaturated soil using Bishop’s Simplified method (1955) which is one method to analyze slope stability in method of slices. In this study, the original formula for Bishop’s Simplified method (1955) of saturated soil were modified by adding the element of matr...
