摘　　要：隧道涌水是隧道施工过程中常见的长期困扰隧道建设者的地质灾害之一,不仅对隧道施工造成极大的安全风险,运营后也存在极大的安全隐患。结合重庆万开周家坝−浦里快速通道铁峰山隧道施工中遇到的集中突出涌水问题,通过多种超前地质探测手段相结合分析涌水类型和判释涌水断面前方的工程地质和水文地质条件,针对性的采取措施,运用Midas-GTS NX有限元软件进行建模分析,对涌水段和两端延伸段原设计衬砌支护参数进行优化,并对防排水措施进行补强,保证了隧道的施工安全和隧道结构安全。Tunnel water gushing is one of the common geological disasters that have troubled tunnel builders for a long time in the process of tunnel construction.It not only causes great safety risks to the tunnel construction,but also has great potential safety hazard in service.Based on the problems of concentrated outburst water inrush encountered during the construction of Tiefengshan Tunnel of Wankai Zhoujiaba-Puli Express Passage in Chongqing,this article analyzed the types of inrush water and the engineering geological and hydrogeological conditions in front of the inrush section by combining various advanced geological detection methods,took specific measures and applied Midas-GTS.NX finite element software to carry out modelling and analysis,optimized the original design lining support parameters of water inrush section and both end extensions,and reinforced the waterproof and drainage measures to ensure the construction safety of the tunnel and the safety of the tunnel structure.
