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 situation of the slope. The sensibility of influence of the underground water and rainfall on landslide stability is analyzed. The conditions of re - sliding of the Gushubao landslide are discussed. The basis on prevention and control works of the landslide is provided.
