摘要
本文应用有限元法研究了几种不规则地形及典型地质构造对粘弹波传播的影响.在SH 波和 P 波垂直入射的条件下,计算了各模型中地震波与地表的位移和加速度的最大振幅分布,同时讨论了它们在工程地震中的可能应用.
In this paper we have simulated the propagation of seismic waves in a viscoelastic medium and calculated the effect of irregular surface topography by using finite element method. Several types of elastic and viscoelastic medium models, such as block structure, mountain top and /or valley with and without a soft layer underneath have been studied. The distribution of maximum amplitude of displacement and acceleration on surface has been calculated in the case of vertically incident SH and P waves from the basement. The possible application in earthquake engineering is also discussed.
