An effective stress numerical model for soil liquefaction, which provides interaction between shearing deformation and transient pore-water pressure development, is presented. Some attractive features of this one-dimensional model are the preservation of the inelastic soil character during shearing, the coupling between shear wave propagation and pore-water pressure development and seepage, and the association of excess pore-water pressure development with the inelastic volumetric deformation of the solid matrix. A comparison is made with results from another effective stress model and a second comparison is made with experimental results from a large scale shaking table.
