| 摘 要： | 在自然界中，岩体均处于一定的原始地应力场中，当岩体由于各种原因产生卸荷将会使岩体形成应力松驰，从而将会使岩体损伤进一步的发展，会对整个岩体的渗流特性产生影响。针对饱和裂隙岩体中在卸荷后的渗透系数与应力强度因子的关系进行了理论研究。

| Abstract: | Rock at depth is subjected to stresses resulting from the weight of the overlying strata and from locked in stresses of tectonic origin.When an opening is excavated in this rock,the stress field is locally disrupted and a new set of stresses are induced in the rock surrounding the opening;Failure of the rock around underground openings will effect the seepage of rock mass.In the paper,the relation between seepage and intensity factors is supposted,and the resultu is fit well with some research findings. |

| Keywords: | fracture failure intensity factors seepage |
