隧道岩溶、断裂带等高压涌水是隧道修建中比较难以解决的问题，隧道突涌水地质灾害频繁发生，成为影响隧道施工和安全的主要障碍。宜万铁路齐岳山隧道所穿越暗河、溶洞、断层破碎带等不良地质高压突涌水地段，给施工带来很大的困难。目前正在施工的齐岳山隧道F11断层破碎带，水压高、水量大、地质条件复杂，成为唯一制约全线的主要技术难题。以平导F11断层的注浆施工治水防坍为实例，介绍F11高水压断裂带治水防坍新方案、新工艺及效果检查新方法等，为以后类似工程积累经验。

Karst caves and faults are big challenges in tunnel construction. Water gushing happens in these strata frequently, which affects construction schedule and construction safety. Qiyueshan Tunnel on Yichang-Wanzhou Railway crosses underground rivers, karst caves and fractured faults in high pressure and water gushing strata. Fractured fault F11, which has high water pressure, large volume of water gushing and complicated geological condition, is the key of the whole tunnel. Taking the technologies of grouting, water control and rock collapse prevention adopted for fault F11 as an example, the authors present the new construction scheme, new construction technology and new effect examination method for water control and rock collapse prevention in high pressure and rich water fault F11. This paper can provide reference for similar projects in the future.
