Abstract

Abstract

Taking two triangular hills joined by a semicylindrical canyon as an example, scattering of SHwaves by complicated terrain were studied. The model was divided into three domains. The wave functions satisfying the boundary condition at each domain were constructed by complex function and moving coordinate methods. The algebraic equations were constructed according to the conjunction of displacement and stress. After solving the equations, the unknown coefficients were acquired. At last, the surface displacement were provided and the influence of different factors such as wave numbers and incident angles were discussed.
- SH-waves,
- two isosceles triangular hills,
- semi-cylindrical canyon,
- surface displacement
