摘要
针对山岭铁路隧道中地下水影响施工过程中隧道围岩和结构的稳定性及后续运营的安全性问题,文章依托怀邵衡铁路中穿越F2断层且易发生涌水、涌泥以及变形坍塌的蜡树脚隧道,运用理论分析和现场实测手段,分析了地下水灾害及其诱发条件,确定了涌水段开挖支护方法,提出了隧道地下水害治理原则和富水段处理方案,获得了较好的效果,可为今后其他类似工程提供参考。
In view of the influence of groundwater in mountain railway tunnel on the stability of surrounding rock and structure of tunnel during construction and the safety of subsequent operation, based on Lashujiao tunnel in HuaiShaoHeng Railway, which passes through F2 fault and is prone to water gushing, mud gushing and deformation collapse, this paper analyzes the groundwater disaster and its induced conditions by theoretical analysis and field measurement, and determines the excavation and support method of water gushing section, puts forward the treatment principle of the tunnel groundwater disaster and the treatment scheme of the rich water tunnel section, which can provide reference for other similar projects in the future.
