Abstract: The earth-rock cofferdam on deep overburden is the main study object. The

cofferdam filling and dam excavation process were numerical simulated using FEM code

ANSYS.Main research focused on stress and deformation characteristic of cofferdam and concrete

cutoff wall during completion and excavation process.Analysis showed that displacements of

cofferdam and cutoff wall distribute well in x, y, z directions with acceptable magnitude, stress

characteristic values are less than design standard. The results indicate that cofferdam and cutoff
