Elasto-plastic Finite Element Analysis of an Earth-Rockfill Dam Based on Generalized plasticity model

Abstract

Abstract. The Pastor-Zienkiewicz-Chan model based on the generalized plasticity theory can simulate the main materials of the earth-rockfill quite well. The three-dimensional modeling of a typical earth-rockfill dam was modeled by HYPERMESH and was implemented into the three-dimensional elasto-plastic program DYNE3WAC through the development of the interface based on FORTRAN. Therefore, the DYNE3WAC can analysized the typical earth-rockfill dam in the impoundingt period and reasonable analysis the dam displacement along the river and settlement and the pore water pressure which can satisfy the dam static development rules. The results show that displacement and pore water pressure are in accordance with the general rule of the earth-rockfill dam and can prepare for the next dynamic analysis.
