| Abstract: | On the basis of an investigation into the gravity dam foundation failure process and state by way of nonlinear FEM numerical simulation, the present standard method of stability examination is analyzed and discussed, in the paper. A new failure criterion—"quasi-elasticity" criterion—is put forward and the corresponding formula is deduced. At last, a comparison dealing with two project instances is made. |
