| 摘 要： | 采用力学理论研究了裂隙岩体渗透系数随埋深及水压力的变化规律，得出渗透系怀埋深水及水压力的关系式。另外，将裂隙岩体介质假设为互相平行的几组裂隙网络，提出了应力与渗流的耦合模型，得出了裂隙岩体与三向应力的关系式。

| Abstract: | The relationship between permeability coefficient and buried depth and water pressure in fractured rock mass is studied by using mechanics theory and the relational expression of permeability coefficient and buried depth and water pressure is obtained. In addition assuming the medium of fractured rock mass as equivalent fracture network in which fractures parallel each other the coupling model of permeability and stress is given and the relational expression between fractured rock mass and three dimensional stress is obtained. Using the equations given and the finite element method,change of permeability of rock mass affected by mining is calculated and proved by test results. |
