DEM simulations of the seismic response of granular slopes

Abstract In this study, a three-dimensional microscale framework utilizing the discrete element method (DEM) is used to examine the seismic response of dry granular slopes under different conditions of ground motions. The presented model inherently accounts for soil nonlinearity and damping in response to shear deformations. The essential characteristics of wave propagation including motion amplification and resonance were observed from the computational results. The impact of the amplitude and the frequency of the input motion on the response of the slope was examined. Comparisons are made between results from DEM simulations and results from existing methods that utilize the Newmark sliding block approach. Generally, these methods predict sliding displacements less than those computed using DEM.
