000004858 520__ $$2eng$$aThe soil liquefaction behavior at very large depths is presently poorly understood, yet this situation commonly occurs at foundations of large earth dams. This paper describes a numerical model, which is used to study the soil liquefaction resistance at high confining pressures. In this research, a two-dimensional numerical model was set up. Base accelerations with different magnitudes and frequencies were applied to the model. The pore water pressure and effective stress at different depths in the model were monitored during shaking. It was found that soil liquefaction resistance increases with the increasing of confining pressure at large depths. At a large acceleration magnitude, the liquefaction can occur at virtually any depth.
