Abstract
Abstract: It is relatively simple for the calculation to the dynamic response of saturated soils to adopt ![]()
-![]()
equations which regard solid-phase displacement and pore pressure as basic unknowns. The pore pressure element based on the fluid-solid coupling dynamic model is developed using ABAQUS which provides users a interface to define a new element (UEL). The results of a numerical example show that the dynamic response can be calculated accurately using the developed pore pressure element. The calculated results obtained with the CEP4P element provided by ABAQUS are obviously different from the real ones.
