摘要

利用曲线坐标描绘局部隆起或凹陷的典型起伏地形，讨论了在介质性质随深度变化的非均匀起伏半空间中的Ｌｏｖｅ波和Ｒａｙｌｅｉｇｈ波的传播规律。给出了决定频散关系的超越方程，并用数值方法计算出了频散曲线。
The problems of dispersion of Love and Rayleigh surface waves in ridge or canyon half space of inhomogeneous medium with varying elastic constants along with depth are studied by means of curvilinear coordinate method. The topography is described in curvilinear coordinate system, and the solutions of wave motion in the half space which satisfy the boundary conditions on the surface are given. The dispersions of Love waves and Rayleigh waves are found to vary with the local topography as well as the frequency. Finally, the dispersive curves of Love waves and Rayleigh waves in ridge or canyon half space are calculated.
