摘要
以半球形沉积谷地对入射平面SH波的放大作用作为算例,提出一种研究地震波斜入射时三维土体动力反应的数值计算方法,求得了地表一些点的位移响应和不同频率下的谱放大系数,以供参考。
Taking the amplification of hemispherical alluvial valley for incident plane SH waves as an example, put forward a numerical analysis method of the scattering problem when the seismic wave oblique incidence, then obtain the displacement response and spectrum amplification fac- tor on different frequencies of some points on the surface, so as to reference.
