The crust is constituted by the rock and a surface layer of soil with depth H over it. The incident seismic wave is a vertical SH shear wave to cause horizontal ground motion.

地壳由半无限大的基岩上一层厚度为H的表土层组成，入射地震波为垂直的SH波，产生水平地面运动。

The height of the sh, ear fine has little influence on the shear stress.

剪片高度对侧面剪应力几乎没有影响。
