Abstract

Rainfall reduces the possibility of increasing landslide instability. In order to study the stability of landslides with multi-stage sliding surface under rainfall conditions, this paper studies the physical and mechanical properties of soils with different moisture contents through direct shear tests of unsaturated soils And then analyze the safety factor and the probability of instability under multi-stage landslide. However, the traditional methods for analyzing the stability of landslides are relatively definite and have certain limitations, and the uncertainties of landslides are not fully considered. Therefore, this paper takes Xiaya River landslide in Baoji City, Shaanxi Province as an example, and uses Monte-Carlo simulation method and Bishop method to analyze the safety factor and the probability of instability of the landslide under different moisture contents.
