The Applications of Concrete Cut-Off Wall in the Reinforcement of the Earth Dam
The concrete cutoff wall is a technology used in reinforcing sick dams more usually in recent years. In the text, the advanced FLAC3D method which is based on 3-D explicit finite difference method, is used to simulate a reinforcement of earth dam using concrete cutoff wall. Through the simulation, Mohr-Coulomb model, elastic model and Goodman element are used to analyse the distribution of the stress and the strain of the dam before and after reinforcement. Consequently, we can evaluate the unti-seepaging effect and raise the possible question.
