Abstract

Matching Mohr-Coulomb parameters to the Drucker-Prager model is deduced and the method of transferring to equivalent sand wall in drain pile ground is introduced in detail. Numerical simulation is conducted in the process of constructing soil dam. The results show that the maximum vertical displacement happens in the center of the dam and the maximum horizontal displacement happens in the toe of the dam. The numerical method in this paper may be used to predict the consolidation process in drain pile ground in the process of constructing soil dam. Those results gained by numerical method may provide reference to engineering practice.
