| 摘 要： | 通过天然裂隙的渗透实验，揭示了三维应力作用下天然裂隙渗流规律，建立了等效法向应力σｎｅ作用下裂隙闭全量△ｂ与渗透系数ｋｆ，σｎｅ与△ｂ的关系式，经过一修正立方定律进行比较，说明所揭示规律的正确性，同时对高应力状态下渗透性态的转化作了初步探讨。

| Abstract: | On the basis of an experimental study, a permeability law of natural fracture under 3D stresses is developed. The relations between fracture closure b and permeability coefficient kf, equivalent normal stress ne and b are also formed. Compared to the modified cub law, the permeability law is proved reasonability. The change of permeability characteristics under high stresses is discussed primarily. |

| Keywords: | fracture permeability coefficient equivalent normal stress fracture closure |
