英文摘要	Abstract Due to the reservoir impoundment, the geological environment in Three Gorges Reservoir area deteriorates, consequently inducing a series of geological hazards. Zhaoshuling landslide is one of the most important landslides in Three Gorges Reservoir area, and its safety seriously affects the planning and construction of the new-established Badong city. The unfavourable change of hydraulic condition, accompanied with earthquake, may cause landslide instability. In this paper, the stability and failure features of Zhaoshuling landslide under the reservoir water and earthquake are researched by discontinuous deformation analysis (DDA) method. The simulated results show that Zhaoshuling landslide is globally stable under the reservoir water and VII earthquake, while considering the degradation effect of rainfall and reservoir water on the strength of the sliding zone, the landslide may be damaged. The landslide damages more seriously at a low water level, the failure mode is creep and traction, and the failure mainly happens at the head and middle of landslide. Therefore, the head and middle of landslide is the key section of prevention and treatment.
