Stability Analysis of Slopes Under Strip Footing Loads
摘要
This chapter presents an introductory exploration into slope stability of soil slopes subjected to strip loading over soft soil beds, utilizing the Finite Element Method (FEM) software, OPTUM G2, through the application of the Strength Reduction Method (SRM). The key objective is to offer a quantitative assessment of slope stability enhancement by placing a locally available stronger soil layer over a weaker subgrade. The Strength Reduction Method (SRM) analysis in this study is carried out using a detailed finite element approach, incorporating both lower bound (LB) and upper bound (UB) limit analysis techniques to ensure a comprehensive evaluation of slope stability. The research investigates various scenarios, including different edge distance ratios (d/B), where ‘d’ represents the distance from the strip footing edge to the slope crest and ‘B’ denotes the strip footing width, as well as different loading conditions. Through this exploration, the chapter aims to contribute to a deeper understanding of slope stability analysis, especially in scenarios where soil stratification plays a critical role.
