Abstract

Abstract

Based on the strength reduction finite element method, the stability of slurry trench of diaphragm in the Beijing metro line 6 Xiyuan station was analyzed. The location and profile of the critical slip surface were calculated. The failure process was also simulated in the commercial software ABQUS. Meanwhile, the effects of various factors such as mud weight and depth, underground water level and surface distributed load were provided in this paper.
