摘要
为解决公路隧道衬砌裂缝处治问题,以昆明绕城高速公路东南段杨林隧道进口右线为依托,通过对滇中地区软岩大断面公路隧道衬砌裂缝位置及特点进行研究分析,制定了针对性的处治措施,同时采取应力消散、灌封修补、粘贴纤维复合材料等加固措施有效控制了衬砌裂缝的发展。研究结果可为同类型隧道衬砌裂缝处治提供参考。
In order to solve the problem of crack treatment in the highway tunnel lining,based on the right entrance line of Yanglin tunnel in the southeast section of Kunming ring expressway,the targeted treatment measures are formulated by studying and analyzing the location and characteristics of cracks in the large cross-section highway tunnel lining of soft rock in the central region of Yunnan.At the same time,the reinforcement measures such as stress dissipation,sealing repair,and pasting fiber composite materials are taken to effectively control the development of lining cracks.The research results can provide reference for the treatment of cracks in the lining of tunnels of the same type.
