摘要
Based on an instance of Wenchuan earthquake area slope, this paper uses the finite difference method FLAC-3D to simulate the effects of the slope under seismic load. In the slope with the FLAC-3D dynamic analysis, the problems about boundary conditions, and the synthesis, input, conversion of the dynamic time history are discussed. Through in-depth dynamical analysis of displacement and velocity, access to the variation of the displacement field and the velocity field under seismic load, the paper shows the displacement and velocity of the mountain slopes in the weak non-continuous medium surface area are the largest.
