| Abstract: | Formulation of a bounding surface model was introduced briefly and implemented into FEM software - MARC. Cyclic simple shear tests were numerically modeled to validate the codes and show the performance of the model. Based on the model implemented, the seismic response of a homogenous level ground was analyzed; and the results were compared with that obtained by equivalent linear method to illustrate the reliability and effectiveness of the model and MARC. The techniques to perform seismic response analysis of earth dams were introduced taking an idealized model dam as an example. |
