Slope Stability Assessment Based on Limit Analysis

Most of the research findings in evaluating slope stability using limit analysis are chart-based. No such stability chart is available to cover a wide range of material strength, slope geometries and external disturbance. Practitioners find it difficult to use the charts for a specific slope project. Compared with a large number of existing commercial softwares based on limit equilibrium and FEM, the practical use of limit analysis is not yet mature. In this paper, the development of a software package for slope stability assessment based on limit analysis is introduced. Several demonstrations of its features and verifications with a commercialized FEM software Phase2 are given. Slope stability assessment based on limit analysis is more efficient and can provide almost identical results compared with Phase2
