摘要
以宜万铁路齐岳山隧道F11高压富水断层地段为工程背景,通过分析现有评定堵水和地层加固作用的方法,对该高压富水断层隧道段的注浆循环和现场试验进行分析,得出2 L/min的检查孔允许出漏水量标准是可行的。文章对高压富水断层地带注浆效果评定的研究,可为后续相同地质隧道施工及制订相关标准提供参考。
In Qiyueshan Yiwan railway tunnel F 11 high water fault location as engineering background, by analyzing existing assessment methods and formation plugging reinforcement effect, the grouting cycle fault High Water tunnel section and field trials analysis, it is concluded that the 2L/min inspection hole allows the water leakage standard to be feasible.In this paper, the study assessed the effect of water, fault zones of high pressure grouting rich, can provide a reference for subsequent geological same tunnel construction and the development of relevant standards.
