摘要推导了粘弹性半空间上弹性层中走滑点源位移的绿色函数的解析近似。这种近似的绿色函数是有用的，因为它可以在断层面上解析积分。与精确解积分的数值积分比较表明，该近似是相当好的。近似的绿色的功能分析积分，以获得位移由于有限的矩形走滑断层在弹性层上的粘弹性半空间。地面位移和角度的变化，从一个模型测量网计算，以说明粘弹性松弛以下的弹性区域中的断裂。
Summary An analytic approximation to the Green's function for the displacements due to a strike slip point source in an elastic layer over a visco-elastic half-space is developed. This approximate Green's function is useful because it can be analytically integrated over the fault surface. Comparison with a numerical integration of the exact solution integral indicates that the approximation is quite good. The approximate Green's function is integrated analytically to obtain the displacements due to a finite rectangular strike slip fault in an elastic layer over a viscoelastic half-space. Ground displacements and angle changes from a model survey net are computed to illustrate the viscoelastic relaxation which follows a fracture in the elastic region.
