Abstract
Rainfall and slope cutting are the most important inducing factors of landslide activities in Southwest China. This paper takes the Simiqiao landslide in Wushan County, Chongqing as an example, obtains the stability and stress–strain field of the landslide under different conditions by field investigation and numerical simulation analysis and further analyzes the influence of rainfall and slope cutting on the stability of the Simiqiao landslide. The conclusions are as follows: the slope cutting has a great influence on the stability of the landslide. For the typical profile, the cutting slope condition under saturated state (coupling condition of rainfall and slope cutting) has the worst stability with a safety factor of 0.886, followed by the cutting slope condition under natural state with a safety factor of 0.939. In this paper, the prevention and control measures for the Simiqiao landslide are also put forward. The research results can provide a reliable reference for disaster prevention and mitigation of similar landslides.
