摘要：

Based on the Biot's theory, dynamic responses of layered saturated soil under moving loads are studied with the transmission and reflection matrices (TRM) methods. Numerical results of the displacements, the pore pressures and the stresses are obtained by performing inverse Fourier transformation in time-space domain. Some numerical examples and corresponding analysis are presented. The presented methodology is validated by comparing solutions with some known results. According to the analysis, it is concluded that the occurrence of softe interlayer in the layered half space enhances the vertical displacement and pore pressure. Comparing with the homogeneous soil, the response of the multi layered half space tends to contain higher frequency components and exhibits larger magnitude.
