| Abstract: | Based on the principle of energy accumulation of liquid diffusing,the pervasion tensor mathematical expression of fractured rock mass is presented. By means of fracture mechanics and damaging theory, the constitutive model of fractured rock mass under complex stress state and the criterion of cracks and studied. The damaging evolution equation of fractured rock mass under the stress state of compression shear and tension is established and the coupling model of unstable seepage field and damaging field of fractured rock mass is presented. According to above of all, the finite element method is programmed and the stability analysis of high slope of the permanent ship lock of the Three Gorges Project is conducted. |
