摘要
在宜万铁路齐岳山隧道F11断层施工中采用信息化跟踪精确注浆法进行注浆堵水加固,有效地解决了注浆设计施工与地质紧密结合难题,优化了注浆加固圈厚度和钻孔数量,较好地提高了功效,攻克了齐岳山隧道高压富水F11断层施工难题。
Qiyueshan Tunnel F11 fault is in the Yichang-Wanzhou Railway Line. The method of information-based track- ing precision grouting is to groutt for reinforcement, which effectively address the design and construction grouting closely integrated with geological problems. It optimized the thickness of grouting and drifting ring number, which greatly improves efficiency, and tackled Qiyueshan Tunnel with anti-slope rich karst and high-pressure water-F11 fault of construction problems.
