摘要: 进行了单、正交裂隙岩体的渗透实验 ,并针对单、正交裂隙岩样在不同温度及应力下的渗流试验特点 ,分析了裂隙结构面变形规律 ,并以此实验成果为基础 ,给出了岩样裂隙结构面温度 -应力 -水力的耦合本构关系式。Abstract: The permeability experiment was made in this paper, and the general regularities of fracture structure face deformation is analyzed for the permeability test under the coupling action between temperature and stress. Based on the test result, a thermal-hydraulic-mechanical coupling constitutive model of the fracture structure face of the rock sample is suggested.
