摘要:: 隧道渗漏水一直影响铁路安全运营，因此需高度重视。成贵铁路隧道所处地质条件复杂，隧道工程占比大，部分隧道建成后出现衬砌拱部、边墙及仰拱填充顶面等渗漏水缺陷。本文针对成贵铁路出现的典型渗漏水情况，提出"拱部注浆封堵、边墙钻孔引排、仰拱降水泄压"的"分区治水"整治原则及相关整治措施。现场工程实施效果表明，整治后隧道渗漏水情况明显改善，后期运营状况良好，可为类似工程提供借鉴。

Abstract:: Great importance shall be attached to tunnel leakage as a common defect hurting the operation safety of railways. The tunnels of Chengdu-Guiyang High-speed Railway are featured with complex geological conditions, and account for a large proportion of the quantity of works, while some tunnels show water leakage at places such as lining arch, side wall, and the top surface of invert filling after completion. In view of the typical cases of water leakage of Chengdu-Guiyang High-speed Railway, this paper puts forward "grouting to seal the arch, drilling to drain the side wall, and dewatering to release pressure in the invert" for the purpose of "leakage control by zone", and the related renovation measures. The effect of field practice shows that the tunnel leakage is obviously relieved after renovation, and the later operation is in good condition, which can provide reference for similar projects.
