Abstract

Abstract: Based on the pseudo-static method, numerical simulation analysis was done on the stability situation of Fujiawu high and steep mountain slope dump in most favorable rainfall saturated and seismic forces combined conditions. Bases on pseudo-static method, the dynamic-fluid-solid coupling stability analysis can simulate the stability situation of dump in two kinds of combination well. The safety coefficient agrees well with other methods, which provides effective method for stability analysis of dump under complicated conditions.

Key words: Dump, Pseudo-static method, Dynamic-fluid-solid coupling, Stability analysis
