| 英文摘要 | A finite difference method for the simulation of multi-component wavefield in viscous extensively dilatancy anisotropic (EDA) media is presented. Transformation of the stress and strain relation from frequency domain to time domain reveals that the viscous effect in EDA media is embedded into the terms of the third derivatives of the strain with respect to time. Numerical examples for viscous EDA. media with dry and saturated cracks are calculated, respectively. In the calculation of the wavefields, the absorbing boundary conditions are used to suppress the artificial boundary reflection, the grid dispersion is suppressed by flux corrective transformation (FCT) technique. Snapshots and seismic records show that the existence of cracks and the material contents in the cracks exhibits significant influences an the wave propagation, especially on the radiation pattern and attenuated factor.
