Simulation of Progressive Failure Process in Rainfall-Induced Landslides

Abstract:

The landslide process and mechanism of rainfall-induced landslides are assessed by using particle flow code in two dimension based on the discrete element method. The formation mechanism of rainfall-induced landslide is revealed by the analysis of displacement field, velocity field and stress of the slope versus time. The fluid velocity and porosity of sample increase gradually with the increase of water head, the violent fluctuation of contact number of movable particles show the violent motion of slope, then the slope maybe slide.
