Abstract: The concrete cutoff wall is a technology used in reinforcing sick dams more usually in recent years. The advanced FLAC3D method which is based on 3-D explicit finite difference method, is used to simulate the effect and working state of earth-rock dam reinforced by concrete cutoff wall. At the meantime, the differences in the stress and strain etc. between the rigid and plastic cut-off wall are also researched; and then that provides the reference to the use and development of this technology.

Key words: concrete cutoff wall, earth-rock dam, reinforcement, numerical analysis
