| Abstract: | In this paper, a substructure method of three-dimensional semi-analysis boundary element is established. The seismic scattering by three-dimensional topography of a hill can be analyzed by the method in frequency domain. By this method, the computational effort and storage space are reduced considerably. At the end, some analysis results are given. |
