    PARTICLE FLOW SIMULATION OF EARTHQUAKE INDUCED DEFORMATION FAILURE OF SOIL SLOPES WITH DIFFERENT GEOLOGICAL FACTORS UNDER EARTHQUAKE

    • This paper aims to study the failure characteristics of the soil slope under the earthquake. It uses particle flow code(PFC2D), simulates the failure process of the soil slopes with different inclinations and micro-parameters under a Wenchuan horizontal seismic wave. The results show that the slope angle mainly affects the failure extent. The steeper the slope is, the deeper the sliding surface is.The micro-parameters control the failure type of the slope. The slide body of the cohesive slope can move as a whole with an arc-shaped sliding surface. Yet the failure of non-cohesive slope is rheologically behaved with a polyline sliding surface whose upper part is steep and lower part is flat.
