多源传感器的车桥联动实时监测与响应特征分析

Real-time monitoring of axle linkage based on multi-source sensors analysis with response characteristics

随着我国基础建设尤其是交通行业的高速发展,桥梁健康监测技术不断取得突破性的进展,使得在运营中的桥梁安全性及人民群众的生命财产安全得到了有效的保障。然而,桥梁健康监测系统只是对桥梁结构本身的特性及响应信息进行监测,没有兼顾即将上桥的车辆情况,缺乏对事故风险的直观评估。因此,本文以二干河桥为例,基于多源传感器,提出了车桥联动监测的方法,对桥梁响应信息及行驶车辆的信息进行实时监测,利用传感器的监测数据进行桥梁响应特征研究;并在二干河桥建立了基于车桥联动的桥梁健康监测管理平台,为桥梁的安全运营提供示范应用。

With the rapid development of China s infrastructure,especially the transportation industry,bridge health monitoring technology has also made breakthroughs,so that the safety of bridges in operation and the safety of people s lives and property have been effectively guaranteed.However,the bridge health monitoring system only monitors the characteristics of the bridge structure itself and the response information,does not take into account the situation of vehicles about to go on the bridge,and lacks a visual assessment of the risk of accidents.Therefore,taking the Erganhe Bridge as an example,based on multi-source sensors,this paper proposes a method of vehicle-bridge linkage monitoring,real-time monitoring of bridge response information and driving vehicle information,and uses sensor monitoring data to study bridge response characteristics.So a bridge health monitoring and management platform based on vehicle-bridge linkage is established in the Erganhe Bridge to provide demonstration applications for the safe operation of the bridge.
