Landslides are affected by engineering geological conditions, precipitation and rainfall. It is of greatly significance to study the causes and treatment methods of landslides to prevent and ensure the safety of people’s lives and property. Base on a case of Songmu landslide, the causes and mechanism of rainfall-induced landslide are analyzed. The stability of landslide under natural and rainfall conditions is analyzed respectively by using finite element strength reduction method and standard calculation method. The influencing factors of landslide are analyzed and the safety and stability of landslide are evaluated. The research results show that the disaster mechanism of Songmu landslide is that rainwater penetrates the clay layer, and the weathered layer is easily softened when rain seepage into landslide. The low strength of the soil induces local deformation and finally occurs sliding. In natural condition, the whole landslide is basically stable, but in saturated condition, the whole landslide should be in unstable state. The formation mechanism of the landslide can provide guidance for the prediction of the landslide deformation and treatment in the future.
