Abstract
This paper presents a new method of fundamental solution (MFS) for solving the scattering of elastic waves in layered half space. Based on dynamic Green’s function in layered half space, the proposed method can efficiently and accurately solve three-dimensional wave motion in a layered medium. Numerical results indicate that the amplification effects of elastic waves in a layered basin is more significant than that in a homogeneous basin, thus it is necessary to consider the bedding structure of the alluvial basin for seismic wave modelling in reality. Keywords: scattering of elastic waves, three-dimensional layered half space, the method of fundamental solution (MFS), alluvial basin.
