摘要：

Deduced the propagation rule of longitudinal and transverse wave.On the basis.of this,propagation rules in attenuated visco-eiastic media and Varied Lame coefficientwere put forward as well.The subsequent numerical analysis found that in a small scopelongitudinal and transverse wave could be considered as homogeneously propagatingwhen faultages and joints were not taken into account.The existence of lane hindered thewave’s propagation,and it made the velocity gradient change in a locat vicinity area.Therefore velocity varied in different direction.
