| 摘要： | This paper describes the utility of a large finite-difference time domain (FDTD) simulation of seismic wave propagation from a spatially and time varying source that generically represents a moving tracked vehicle. The focus is the computational approach and requirements for the long- duration simulation, the geologic model, the moving vehicle force algorithm, the resulting particle velocity wave fields, and example applications of the data. The 8th order FDTD simulation consisted of parallel computations based upon a domain decomposition strategy. The computations were performed using a Sun workstation cluster at the U.S. Army Engineer Research an |
