城市下穿通道结构健康监测及安全评价

Structural Health Monitoring and Safety Evaluation of Urban Underpass

城市隧道长时间的运营使用过程中,由于隧道自身施工缺陷或养护不到位等问题,容易引发隧道结构变形、病害等,对隧道结构安全造成隐患。因此必须准确掌握隧道结构安全状态,进而采取结构安全控制措施,以确保城市隧道运营安全。城市下穿通道作为城市快速路的重要组成部分,其重要性不言而喻,以扬州市润扬北路、泰州路下穿通道为依托,开展隧道结构变形监测和病害调研,评价隧道结构安全状态,并提出相应的养护措施。希望能为类似城市下穿通道的结构安全监测和评价提供一定的借鉴和参考。

During the long-term operation of urban tunnel,due to the defects of tunnel construction or its inadequate maintenance,it is easy to cause the tunnel structure deformation,disease and other problems,which will bring out the hidden dangers to tunnel structure.Therefore,it is necessary to clarify the safety state of tunnel structure so as to take the control measures of structural safety and to ensure the operation safety of urban tunnel.As an important part of urban expressway,the importance of urban underpass is self-evident.Based on the underpasses of Runyang North Road and Taizhou Road in Yangzhou,the structural deformation monitoring and disease investigation of tunnel are carried out.The tunnel structural safety status is assessed and the corresponding maintenance measures are put forward.It is hoped to provide a certain reference for the structural safety monitoring and evaluation of similar urban underpasses.
