摘　　要：本文针对公路隧道混凝土衬砌施工中存在质量缺陷,导致裂缝结构产生的问题,开展对裂缝补修技术的研究。结合化学方法,实现公路隧道衬砌混凝土裂缝灌浆;注浆后,对混凝土裂缝表面进行防护处理;通过导流与围堰的设置,实现对裂缝渗漏的修补处理。通过实例证明,应用新的补修技术后,裂缝位置的渗水量得到了有效控制,进一步促进了公路隧道混凝土衬砌结构的稳定性提升。In view of the problems caused by the crack structure in the concrete lining construction of highway tunnel,the paper studies the crack repair technology.Combined with chemical method,realize the grouting of concrete crack of highway tunnel lining;after grouting,protect the concrete crack surface;repair the crack leakage by setting the diversion and cofferdam.The example proves that after the application of the new repair technology,the water seepage of the crack position is effectively controlled,which further promotes the stability of the lining structure of the highway tunnel concrete lining.
