针对粘弹性裂隙型单斜介质,本文应用高阶交错网格差分法,对其传播快照以及多方位地面三分量记录进行模拟,结果证明了裂隙填充物的性质引起的各向异性与粘弹性性质对单斜介质波场有明显的影响,总结了不同观测方位地震记录呈现出的规律性,这为进一步了解波场在介质中的传播情况,提出更合理的理论模型,提供一种尝试。
For the viscoelastic fracture-type monoclinic medium, the high-order staggered grid difference method is used to simulate the propagation snapshots and multi-directional terrestrial three-component records. The results show that the anisotropy and viscoelastic properties of the fracture filler It has obvious influence on the wave field of monoclinic medium and summarizes the regularity of the seismic records in different observation azimuths. This provides a more reasonable theoretical model for further understanding of the wave field propagation in the medium.
