SUSCEPTIBILITY ANALYSIS OF GEOLOGICAL DISASTERS OF ENGINEERING SLOPE INDUCED BY THE COUPLING OF EXCAVATION AND RAINFALL
The large rainfall in the mountainous area of South China is one of the important factors affecting the stability of the slope.In recent years,geological disasters induced by the coupling of human engineering activities and rainfall environment have occurred frequently.Taking a high slope in Zhongkai District,Huizhou City,Guangdong Province as an example,several indicators were selected and the bishop method was used for triggering mechanism analysis of geological disasters that may occur in the slope after engineering activities,and then preventive suggestions were put forward.The research shows that heavy rainfall can stimulate and accelerate the artificial excavation slope,and the increase of excavation depth is superimposed with rainstorm weather,which eventually leads to the resurrection of landslide.
