摘要 

为了得到TTI介质中传播的纯纵波和纯横波波场,采用旋转交错网格高阶有限差分法对TTI介质中传播的地震波场进行了数值模拟,并利用qP波、qSV波、SH波的极化方向相互垂直的特性,来实现qP波、qSV波、SH波的分解。通过对均匀介质模型和复杂层状介质模型分解前后波场快照和地震记录的对比,验证了本文方法的正确性。

Abstract

In order to obtain the pure P and SV and SH waves in the TTI media. The rotated staggered grid finite-difference method was used to simulate the waves propagate in the TTI media, and the properties of the P、SV、SH polarization directions perpendicular to each other was used to decompose the coupled waves. This method is testified by thecomparison of the original wave-field and the decomposed wave-fields of a homogeneous media and a complex 6 layers media.
