The Stress and Displacement Analysis of the Cut-Off Wall for the Deep Overburden Dam

摘要

The Duncan-Chang nonlinear constitutive model is used to carry out a three-dimensional finite element analysis of Xia Ban Di deep overburden dam with clay core. The regularities of the horizontal displacement, vertical stress and stress level for the cut-off wall are studied in this paper, and the paper provided reference for the dam stability and anti-seepage treatment of the cut-off wall with deep overburden.
