调查中发现，穿过断层的巷道在开掘时地压显现更为明显，变形大，维护困难。沿断层掘进的巷道靠断层侧巷帮变形严重，锚喷支护巷道的锚杆往往不受拉力，无法起到支护的作用。在一段时间内巷道保持相对稳定，但一旦支护体受到破坏，巷道变形即加快，且在断层下盘容易发生局部冒顶。

結果 (英文) 1:

Investigations found that pressure of tunnel dug through the fault is more obvious, deformation, difficult to maintain. Drivage roadway along the fault by fault side serious deformation of bolting and shotcreting roadway anchor Rod tension are often not, unable to play a supporting role. Roadways remained relatively stable over time, but once the body is destroyed, roadway deformation that is accelerating and the footwall of local caving-prone.

結果 (英文) 2:

The survey found that across the fault in the tunnel digging when pressed to show more obvious, large deformation and difficult to maintain. Roadway Driving along the fault by fault deformation serious side roadway, bolting and shotcreting roadway bolt tension is not often, they can not play a supporting role. Over time the roadway remained relatively stable, but once the supporting body damage, roadway deformation that is accelerating, and in the footwall prone part roof.

結果 (英文) 3:

The survey found that the tunnel through the fault in the digging when the ground pressure is more obvious, large deformation, difficult to maintain. Along the fault of the roadway along the fault side of the roadway to help serious deformation, bolt and shotcrete support of the bolt is often not pulling force, can not play the role of support. In a period of time the roadway remained relatively stable, but once the support is damaged, the roadway deformation is speeding up, and in the footwall prone to local caving.
