Abstract

The particle flow discrete element method to research ten groups of Mian County Yangjiawan accumulated layer landslide failure mode and the movement process was studied by numerical simulation. By comparing the simulation parameters of rock and soil mass calibrated by PFC^2D biaxial simulation test and macroscopic parameters measured in laboratory experiments, the meso parameters of accumulated layer landslide were determined. Then, the calibrated meso parameters were applied to the accumulated layer landslide model, simulation study on the failure mode and movement process of landslide. The results show that the cumulative creep deformation of landslide in the initial stage, landslide body extrusion toe, the shear failure, and upward traction development made the whole landslide along the contact surface damage decline and accumulation in the slope toe, showing a typical traction type progressive failure, results are basically consistent with the actual situation. The results show that the applicability of the simulation of the particle flow method of accumulated layer landslide failure and the movement process is high, the landslide prevention and control have a certain reference value.
