| 摘 要： | 通过引入渗透压力附加柔度张量的概念以及考虑渗透张量的演化行为，详细研究了裂隙岩体渗流与损伤变形的相互作用机理。在此基础上建立了基于两场耦合的裂隙岩体渗流损伤模型。工程算例结果表叫，当存在地下流体流动时，渗流对岩体变形破坏以及损伤变形对岩体渗流场的影响是不可忽略的。

| Abstract: | By introducing a concept of additional hydraulic pressure-induced flexibility tensor and considering effects of damage behavior on permeability tensor of fractured rock mass,the coupled behavior of stress and seepage is analyzed. Based on above analysis,a model for coupling analysis on fluid flow and damage is developed. The results obtained from theoretical and practical analysis show that the influence of hydraulic pressure on damage behavior and effects of damage on distribution of hydraulic pressure can not be ignored when there is fluid flow in fractured rock mass. |
