摘要：

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.
