摘要
从流体扩散能量叠加原理出发，建立了裂隙岩体介质的渗流张量解析表达式。综合应用断裂力学与损伤理论，探讨了复杂应力状态下裂隙岩体的本构关系以及压剪裂纹的起裂准则，建立了裂隙岩体在压剪、拉剪应力状态下损伤演化方程，提出了渗透张量随裂隙损伤发展的关系以及裂隙岩体非稳态渗流场与损伤场耦合模型。
Based on the principle of energy accumulation of liguid diffusion,this paper puts forward the analytical expression of pervasion tensor of fractured rock mass.By means of fracture mechanics and damaging theory,the constitutive model of fractured rock mass under the complex stress state and the criterion of cracks are studied.The damaging evolution equation of fractured rock mass under the stress state of compression shear and tension shear is established and the coupling model of unstable seepagefield and damaging field of fractured rock mass is presented.
