Abstract: Kinematics plays a very important role in the behavior of landslides in discontinuous media. Discontinuous Deformation Analysis (DDA) is applied to simulate the whole movement process of Qianjiangping landslide located in the area of Three Gorges Reservoir. The simulation scheme is mostly based on the characters of geology and landform; and the mesh of elements is based on different types of rock and geological joints. The gradual failure and the movement process after sliding are simulated, all of which are in the working conditions of reservoir impoundment and rainfall. The results of simulation indicate that the local failure in the toe of the slope is the beginning of the Qianjiangping landslide; and it gives a further dragging on the upside sliding body; and finally the landslide is triggered by groundwater pressure.

Key words: Qianjiangping landslide, DDA, kinematics, numerical simulation
