| 摘 要： | 隧道断层（F2）为张性正断层，破坏原岩中较为对称的应力平衡，加之带内岩石破碎，节理裂隙发育，使得断层更加容易坍塌和涌水。建议采用稳定掌子面法和专门支护保证硐室稳定。

| Abstract: | The fault F2 in the tunnel is a tension fault, which has broken the original symmetrical dynamic equilibrium in the rock. Moreover, the fracture of rock and development of joint fissure cause the fault to collapse and leak more easily. We suggest that the stable work area method and special support must be taken in ortder to guarantee the stability of the cavity. |
