摘要
本文建立了一种三维半解析边界元子结构法。这种方法可在频域就三维轴对称凸起山包对地震波的散射进行分析。这种方法节省存储空间、计算工作量小。另外还叙述了拐角的处理方法。
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.
