摘　　要：在我国大力倡导"互联网+"背景下,越来越多的水下隧道搭建起以传感技术为基础的结构健康监测系统,该系统实现了运营期隧道结构安全的损伤识别和量化分析,给隧道养护管理带来了便利。然而,部分水下隧道结构健康监测系统在使用过程中出现了数据无法读取、评估决策机制失效等问题,给管理者带来不便。研究项目以南京某隧道、扬州某隧道结构健康监测系统为研究对象,采用历史资料查阅、现场检查、仪器测试等手段,详细分析了隧道结构健康监测系统的运营现状,并探讨了水下盾构隧道结构健康监测系统实施的注意事项及发展趋势。Under the background of China’s vigorous promotion of"Internet+",more and more underwater tunnels have built a structural health monitoring system based on sensing technology,which realizes the damage identification and quantitative analysis of tunnel structure safety during operation.It has brought convenience to tunnel maintenance management and has gradually become an important decision-making basis for managers to rely on.However,some underwater tunnel structural health monitoring systems appear to be incapable of reading data and invalidating the decision-making mechanism during use,which brings inconvenience to managers.The research takes a tunnel in Nanjing and a tunnel health monitoring system in Yangzhou as the research object,and analyzes the operation status of the tunnel structure health monitoring system by means of historical data review,on-site inspection and instrument testing,and discusses the precautions and trends in the implementation of underwater tunnel structural health monitoring systems.
