齐岳山隧道全长10 528 m,是在建铁路宜万线第三长隧道,隧道进口采取反坡施工。在进口齐岳山背斜地段施工过程中,先后揭示了6个大型岩溶,充填物有水、淤泥、粘土和块石土等多种,水量、水压不等。根据充填介质和工程及水文地质特征,施工中有针对性地采取了释放、排泄、注浆等不同措施,使不同类型的岩溶得到了有效的治理。
Qiyueshan tunnel with a length of 10528 meters is the 3rd long tunnel on Yichang - Wanxian railway. Downgrade construction was adopted on the entrance section. In the anticline region six big karsts were encountered which were filled with water, slit, clay, and rabble stones, the amount and pressure of water being varied. According to the features of the filling materials and engineering geology and hydrogeology, different measures were adopted such as relieving, drainage, grouting, etc. , which tackled the karsts of different types effectively.
