The seabed is assumed to be transversely isotropic fluid-saturated elastic porous medium. Based on the anisotropy theory and Biot dynamic consolidation equations, this paper has established a 3D-dynamic seabed model in u-w-p form and defined anisotropic indicators ξα, ξβ, m for the first time. The governing equations are solved by the Wilson-θ finite element program of DSFEM, and the numerical model is verified by test results. The computation results indicate that the amplitude of the pore water pressure decays more quickly with higher wave heights, shorter wave periods, or in shallower water depths.
