摘要
地铁隧道的构造及运营环境特殊,隧道结构出现的病害较多.文章通过采用多种仪器设备对隧道进行外观检测和无损检测,得到了隧道衬砌裂缝、衬砌厚度、混凝土强度等信息.检测结果表明:隧道虽然存在裂缝、渗水和露筋等病害,但是综合影响不大,对隧道正常运营不构成威胁;依据相关规范和标准进行安全等级评定,全等级评定结果为C级,不影响通道运行安全.
Abstract
due to the special structure and operation en-vironment of subway tunnel,there are many diseases in tunnel structure.By using a variety of instruments and equipment to carry out the appearance detection and non-destructive detection of the tunnel,the information of tunnel lining crack,lining thickness and concrete strength is obtained.The detection results show that although there are cracks,water seepage and rebar exposure in the tunnel,the comprehensive influence is small,which does not pose a threat to the normal operation of the tunnel;according to the relevant specifications and standards,the safety grade is evaluated,and the full grade evaluation result is grade C,which does not affect the operation safety of the channel.
