摘　　要：针对大瑞铁路高黎贡山隧道1号竖井突水淹井的技术难题,通过水文地质分析及现场试验,探讨了井筒施工中构造破碎带突水淹井的成因,采用“复合水泥浆止水垫+靶向注浆”的综合治理技术,解决了井筒施工中的突水问题,恢复了淹水竖井的功能。研究结果可为类似工程提供技术借鉴。In view of the technical problems of water inrush and flooding in shaft No.1 of Gaoligongshan Tunnel of Darui Railway,the causes of water inrush and flooding in structural fracture zone in shaft construction were discussed through hydrogeological analysis and field test.The comprehensive treatment technology of"composite cement slurry water stop pad+targeted grouting"was adopted to solve the water inrush problem in shaft construction and restore the function of flooded shaft.The research results can provide technical reference for similar projects.
