Based on the indoor test of model, the differences of vertical bearing capacity of closed and single underground diaphragm walls were discussed, the software FLAC-3D was used in numerical simulation in order to supply the indoor test of model, the influences of deformation modulus, density, cohesion and internal frictional angle on vertical bearing capacity of closed underground diaphragm walls were studied. The result showed that the mechanism of outside friction resistance in closed and single underground diaphragm walls were mostly the same, but the mechanism of inside friction resistance in closed underground diaphragm wall was more complex because of the existence of core.
