摘要：
We present an analytic solution of two-dimensional scattering and diffraction of plane P and SV waves by circular-arc alluvial valleys with saturated soil deposits and water. We use the Fourier-Bessel series expansion technique with the deposits simulated by the Biot dynamic theory for saturated porous media, the half space assumed to be elastic single-phase media, and the water in the valleys simulated by perfect fluid. Numerical results are given to show the displacement amplitudes on the valley floor. Our analysis indicates that the surface displacement amplitudes of the valley floor changes with the positions of the observation points apparently.
