Abstract
In order to analyze dynamical pore water pressure in saturated asphalt concrete pavement, a dynamic Finite Element Method (FEM) is derived by Galerkin Weighted Residual Method, based on Biot's consolidation theory and viscoelastic incremental constitutive equations. Using this FEM scheme, a one-quarter instance of double disk load model is numerated under semi-sinusoidal load and with Burgers viscoelastic constitutive equations to illustrate the spatial distribution and fluctuation of effective stress and pore water pressure according to time. Influences of the two key parameters — permeability coefficient and loading speed on the maximal pore water pressure are emphasized on, and a correlative equation about them is fit.
