摘要
利用流体扩散能量叠加原理，建立了裂隙岩体介质的渗透张量数学表达式综合运用断裂力学和损伤理论，探讨了复杂应力状态下多裂隙岩体的本构关系以及压剪裂纹的启裂准则，建立了裂隙岩体在压剪、拉剪应力状态下损伤演化方程，给出了裂隙岩体损伤场与渗流场耦合方程在此基础上。
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.
