| 摘 要： | Introduction There are various factors affecting the propagation of earthquake waves. Usually these fac- tors include the earthquake source, the path and the site effects. Simulations of the earthquake wave propagation and the strong ground motion are an adequate way to exhibit these factors (Virieux, 1986; Levander, 1988; Frankel and Vidale, 1992; Frankel, 1993; Graves, 1993, 1996a; Olsen et al, 1995; Pitarka et al, 1996; Pitarka, 1999). The most popular numerical method in use is the gri…

| Abstract: | Strong ground motion of an earthquake is simulated by using both staggered grid finite difference method (FDM) and stochastic method, respectively. The acceleration time histories obtained from the both ways and their response spectra are compared. The result demonstrates that the former is adequate to simulate the low-frequency seismic wave; the latter is adequate to simulate the high-frequency seismic wave. Moreover, the result obtained from FDM can better reflect basin effects. |
