Faults are widely existed in crust. They effect the elastic wave scattering as site condition. The analysis of wave propagation by fault is important both in theory and engineering.

断层广泛存在于地壳中，作为场地条件影响地震波的传播，研究断层对弹性波散射的影响对理论研究和工程应用均有十分重要的意义。

Compared with the seismic responses of free homogeneous half space, the results present the effect of vertical cracks on the propagation of seismic wave and the ground motion near the fault site.

计算结果与均匀半空间自由场做了对比，以说明竖向地裂缝对地震波传播和附近地面运动的影响。
