摘　　要：随着公路隧道的多年运营,会产生多种病害,其中隧道衬砌渗漏水病害较为常见。衬砌渗漏水病害会造成钢筋锈蚀、混凝土开裂、衬砌保护层厚度不足等问题,形成重大隐患,严重威胁公路隧道的使用功能以及安全性。以伊犁G217线K730+577玉希莫勒盖隧道提质升级改造项目为例,通过现场调查,结合现场检测结果,分析了公路隧道衬砌渗漏水病害的成因,介绍了隧道衬砌注浆技术在实际工程中的应用,为今后的公路隧道衬砌渗漏水病害处治提供参考。With many years'operation of highway tunnel,a variety of diseases will occur,among which the water leakage disease of tunnel lining is more common.The water leakage disease of lining will cause problems like reinforcement corrosion,concrete cracking and insufficient thickness of lining protective layer,form major hidden dangers,and seriously threaten the use function and safety of highway tunnel.Taking the upgrading and reconstruction project of K730+577 Yuximolegai tunnel of Yili G217 line as an example,the causes of water leakage diseases of highway tunnel lining are analyzed through on-site investigation,the application of tunnel lining grouting technology in practical engineeringis introduced by combining with the on-site detection results,so as to provide reference for the treatment of water leakage diseases of highway tunnel lining in the future.
