Abstract
The stress and strain analysis for earth rock-fill Dam has been caryed out by the Duncan-Chang constitutive model using the subroutine in the finite element analysis software ABAQUS. When considering the effect of seepage, the position of the exit point and the phreatic surface, as well as the total head are calculated through iteration at first, the seepage forces are then determined according to the hydraulic gradient. In the consequent stability analysis, seepage forces, and buoyancy are loaded on the construction period dam. The stress and strain in stable seepage period for earth rock-fill dam were analyzed. The analysis results demonstrated that this method is reasonable and efficient for dam stress-strain during stable seepage period.关键词
