     based on the theory of porous media (tpm), a mathematical model of a two-dimensional incompressible fluid-saturated elastic soil is established, and the periodic boundary conditions are presented to analyze the transient dynamic response of this soil under a moving cyclic loading. the differential quadrature method (dqm) and the second-order backward difference scheme are applied to discretize the governing equations on the spatial and temporal domains, respectively. as application, a typical two-dimensional wave-induced transient problem with a seabed of finite thickness is analyzed, and the numerical results are compared with the analytical results presented in the present work. in addition, a transient dynamic response of fluid-saturated soil under limit moving vehicle loadings is studied. the effects of the velocity of vehicle and the volume fraction on the settlement and the pore water pressure are studied.
