摘要

盾构隧道是城市及软土地下基础设施的主要结构,保证其在建设和运营期的安全至关重要。盾构隧道纵横向变形、管片接头张开量以及渗漏水等病害的监测更是掌控其安全性态的几个重要方面。在物联网的时代发展背景下,本文针对隧道结构特点和环境条件,首先介绍了自主研发的TJ_UWIS双轴倾角传感器、基于LVDT的裂缝无线传感器、基于电导率的渗漏水无线传感器,并基于Zigbee构建了具有二层网络拓扑结构的无线感知网络(Wireless Sensoring Network,简称WSN),该WSN技术可实现盾构隧道结构变形、接缝张开以及渗漏水的实时动态监测。通过上海地铁隧道以及越江大直径公路隧道的现场案例应用得到验证,该方法可以不受运营列车通行影响,真正实现运营隧道全天候实时监控,为隧道安全提供技术支持,有效保障隧道运营安全。
Shield tunnel plays an important role in the underground infrastructure for cities in soft ground.It's safety during the construction and operation thus should be most crucial.Monitoring the tunnel performance of deformation,joint opening and leakage is an effective way to control the lifetime safety of shield tunnel.In this paper,a "smart" sensing system coupling the MEMS inclinometer,LVDT displacement sensor and electronical conductivity sensor with Zigbee-based Topological network is firstly proposed in brief and subsequently validated by several in-situ full scale test segmental lining structure for both the Shanghai metro tunnel and Under-river large road tunnel.The merit of this system,compared to the conventional monitoring system,is its ability of real-time dynamic monitoring regardless of the running of metro tunnel,which has been well recognized in these real case applications.
