Three-dimensional scattering and diffraction of plane Rayleigh-waves bya hemispherical alluvial valley with saturated soil deposit

ZHAO Cheng-Gang,HAN ZhengSchool of Civil Engineering and Architecture, Beijing Jiaotong University, Beijing 100044, China  
The three-dimensional scattering and diffraction of plane Rayleigh-waves by a saturated hemispherical alluvial valley is studied in this paper. In order to consider the real site conditions for the problem, the hemispherical alluvial valley is assumed to be saturated porous media, which is more reasonable than to assume it as an elastic single-phase media; and the half space is assumed to be an elastic single-phase media. We use Fourier-Bessel series expansion technique to formulate the analytic solutions. The results of surface displacement amplitudes of the solutions are presented. The effects of incident wave frequency and the feature of the surface displacement amplitudes are discussed. The results are compared with those of the saturated hemispherical alluvial valley being assumed to be an elastic one-phase media.
