Z—D横向各向同性介质中的地震波

SEISMIC WAVES INZ-D TRANSVERSELY ISOTROPIC MEDIA

在本文中,我们比较详尽地研究了二维横向各向同性介质中地震波势位解,发现:在二维条件下,似P波、似SV波与似SH波解耦。通过对质点振动的研究发现:似P波振动方向一般与波动传播方向不一致,似SV波引起的质点振动方向与波动传播方向不垂直,似SH波引起的质点振动方向与波动传播方向绝对垂直。

In the paper, We studied the potential solution of seismic waves in Z-D transversely isotropic media, and found that in the case of Z-D qp, qsv and qsH waves are uncoupled. By the study of particle-motion direction, we found that the direction of qp particle-motion does not coicide with the propagat- ing direction, for qsv waves two directions are out of the vertical, generally, and for qSH waves not only the directions but also the ray plane are vertical each other. icqpQSHSHSHareci
