| 英文摘要 | With the continuous research in seismology, the influence of the heterogeneity caused by microstructure interactions of the medium on seismic wave propagation has been paid more attention. Wang et al. (2020) proposed to describe the complex microstructures of the medium in the framework of the generalized continuum mechanics theory, and derived the asymmetric elastic wave equations containing the characteristic length scale parameter of the medium. In addition, scale effects of seismic wave propagation will appear when considering microstructures of the medium. In this work, in order to better analyze the scale effects and extract the new components of wave fields owing to the microstructure interactions, we propose an optimized finite-difference (FD) method based on the improved bat swarm optimization (BSO) algorithm. Then the optimized FD method is used to perform numerical modeling for the asymmetric elastic wave equations considering microstructures of the medium. Numerical dispersion analysis indicate that the optimized FD method has high accuracy. According to the numerical modeling results obtained by the optimized FD method, scale effects of seismic wave propagation can be clearly observed when considering microstructures of the medium. |
