摘要
为了解决公路山岭隧道二次衬砌结构厚度不足、开裂等病害导致的承载力不足问题,并减少现浇套拱加固方法造价较高、封闭交通时间较长的缺陷,介绍了预制混凝土衬砌板(PCL板)在隧道修补加固中的应用,包括其结构构造、设计流程与施工流程,可为今后国内隧道衬砌病害处理提供参考。
In order to solve the problem of insufficient bearing capacity caused by diseases such as insufficient thickness and cracking of secondary lining structure of road rock tunnel,and to reduce the defects of high cost and long closed traffic time of cast-in-place arch reinforcement method,the precast concrete lining(PCL)plates are introduced,including its overall structure,design and construction process,which can provide reference for the treatment of tunnel lining diseases in the future.
