Herein an effective stress analysis method using a multiple shear plasticity model and a concept of liquefaction front was used to investigate the static and dynamic.

The effective stress method of dynamic analysis is used to explain the performance of Douhe Earth Dam during Tangshan Earthquake on July 28, 1976.

Using the well-known weighted residual method and finite element procedure, a nonlinear static analysis parallel with effective stress dynamic analysis has been made.
