摘要

///Using the method of finite difference time domain to simulate the seismic wave can obtain much more information of the wave field. It is very effective to investigate the seismic wave field on complex geological background. In this paper, the finite difference time domain (FDTD) was briefly introduced. For the Anxin-Kuancheng deep seismic sounding profile conducted on April 2002, the two-dimensional full wave numerical simulation was performed with FDTD method, as well as the perfectly matched layer as the absorbing boundary condition. Discussing and comparing the FDTD simulation synthetic seismograms with the recorded sections and the synthetic results given by ray tracing method, the effectiveness of the finite difference time domain method for the simulation of the seismic wave propagation has been proved.
