摘要
天山隧道穿越断层破碎带,埋深88m,地下水发育。由于突发大面积涌水,造成地表塌陷。介绍了采用地表深孔注浆固结止水方法加固围岩,既可保证施工安全,又能保护水资源。
Tianxinshan Tunnel goes through fault fracture zone, with a burial length of 88m and developed ground water. Owning to the sudden outburst of water in a large area, the ground surface is collapsed. This paper introduces the method of blocking water and strengthening of the surrounding rock with deep hole grouting, which not only ensures construction safety, but also protect water resources.
