Abstract：The Gushubao landslide had ever blocked the traffic of the Shuibuya water control project site. Based on the geological background and the site engineering geological characteristics of the Gushubao landslide of Qingjiang River，the nonlinear finite element method is applied to study the stability of the slope during rainfall. The sensibility of influence of the underground water and the rainfall on landslide stability is analyzed. The influence of transient saturated zone in the slope due to rainfall to the stability on the slope is discussed. The conditions of re-sliding of the Gushubao landslide are discussed. The basis of prevention and control works of the landslide is provided.
