| 摘 要： | 利用半空间场地用单相介质动力学理论模拟，并略去阻尼项的影响，首次推导出了三维半球形凹陷谷场地在平面Rayleigh波入射下散射问题的解析解。确定局部场地的三维波场分布，给出半球形沉积谷场地地表位移分量，分析了入射波频率对场地震动的影响，并进一步与单相弹性介质情况下的地表运动进行了对比。

| Abstract: | Utilizing deposits simulation of the half space assumed to be single-phase media and neglecting the influences of damping term the analytic solution of the scattering questions of plane Ratleigh waves in hemispherical canyon is derived at the first time. The field distribution of three-dimensional waves in local site is determined as well as the displacement component of ground. The influences of incident frequency on ground earthquake are analyzed. Further comparison is also made between ground motion under the circumstance of single-phase media. |
