桥梁动态监测系统在城市桥梁管理中的应用

Application of Bridge Dynamic Monitoring System in Urban Bridge Management

桥梁动态监测为近年来应用于城市桥梁管理中一种新技术。通过在桥梁上安装传感器,对桥梁变形、振动响应、应力、裂缝、位移、荷载及环境等数据进行实时感知,运用无线网络将感知数据传输至服务器,通过专业软件对数据进行分析。结合赤峰市红山区松州桥实例,通过对动态监测系统数据进行分析,表明桥梁挠度逐渐增大,桥梁承载能力逐渐下降,桥梁动态监测为桥梁日常养护及维修加固提供数据支持,为城市桥梁管养者提供科学、实时的决策依据。

Bridge dynamic monitoring is a new technology applied to urban bridge management in recent years.By installing sensors on the bridge,the data such as deformation,vibratory response,stress,crack,displacement,load and environment are sensed in real time.Wireless network is used to transmit the sensing data to the server and professional software is used to analyze.Based on the example of Songzhou bridge of Hongshan District in Chifeng,the dynamic monitoring system data analysis shows that the deflection deformation of the bridge is gradually increasing and the carrying capacity of the bridge is gradually decreasing.The dynamic monitoring data provides data support for daily maintenance and maintenance of bridge and provides scientific and real-time decision-making basis for urban bridge custodian.
