半覆盖层
半覆盖层-
分析结果显示，半空间中地表覆盖层参数的变化对入射SH波的散射影响较大，可明显改变结构周边动应力系数及地表位移值的分布。
The results show that the parameters of surface overburden layer in half-space have great influence on the scattering of SH-wave , which can change the distribution of dynamic stress concentration coefficient and surface displacement around the circular inclusion and circular cavity .
