000010806 520__ $$2eng$$aUsing the Green’s function, the complex function and moving coordinates, an analytical method is developed for scattering of SH -wave by a semi-cylindrical hill above a subsurface crack. Firstly, a suitable Green’s function is constructed, which is the fundamental solution of displacement field for an elastic half space with a semi-cylindrical hill under an out-plane harmonic line source loading at an arbitrary point in matrix. Secondly, based on the problem of scattering of SH wave by a semi-cylindrical hill, the Green’s function is employed to construct a subsurface crack. Finally, the displacement field of semi-cylindrical hill above a subsurface crack under SH wave is given. The calculating results of the hill motion are plotted to show the influence of crack on the surface displacement, which demonstrates that the presence of the crack has obvious earthquake damping function under certain conditions.
