摘　　要：裂缝是混凝土最常见的病害,地下综合管廊如果出现裂缝,不仅会影响管廊结构的整体受力性能,还可能导致管廊发生渗漏水现象,严重影响地下综合管廊后期的使用和运营。包头市110国道综合管廊项目针对施工过程中出现的混凝土裂缝,采用了高压注环氧树脂法对裂缝进行修复处理,修复效果较为显著。Cracks are the most common disease of concrete.If cracks occur in the underground comprehensive pipe gallery,it will not only affect the overall mechanical performance of the pipe gallery structure,but also cause water leakage in the pipe gallery,which will seriously affect the use and operation of the underground comprehensive pipe gallery in the later stage.In view of the concrete cracks in the construction process of the comprehensive pipe gallery project of Baotou National Highway 110,the high-pressure epoxy resin injection method was adopted to repair the cracks,and the repair effect was relatively significant.
