| 摘 要： | 采用大圆弧面来模拟半空间表面，利用波函数展开法在频域内给出了圆弧形沉积谷地形对平面P波三维散射的一个解析解，并以此解答为基础，进一步分析了入射波频率和入射角度对圆弧形沉积谷地场地反应的影响。数值结果表明，入射波的频率和入射角度对圆弧形沉积谷地场地反应有重要影响。

| Abstract: | The 3-D scattering of plane P waves by circular arc alluvial valleys is studied. The circular surface assumption is used to simulate half-space surface; and the wave function expansion method is used to give the analytical solution in frequency domain. Based on the solution, the effects of the incident frequency and incident angle of plane P waves on the dynamic response of circular arc alluvial valley are discussed. The numerical results show that the surface displacement amplitudes significantly depend on the incident angle and the incident frequency of the incident P waves. |
