| Abstract: | The stability of the gravity dam against deep slide is very import for its design.Base on rigid limit equilibrium method for the analysis standard double slide mode in the Gravity Dam Design Code,A new approach of rigid limit equilibrium for the calculation of stability safety factors was proposed.The stability safety factors were obtained by the new approach through an engineering practice.The wedge stability analysis ultimate method specified in the Design Code was discussed.And the reasonable expression of the special double slide mode stability analysis ultimate method was proposed.Through the engineering practice,the result of the new expression is apt to safety. |

| Keywords: | gravity dam stability against deep slide rigid limit equilibrium method subentry coefficient limit state. |
