大跨径桥梁结构健康监测系统改造

江阴大桥结构健康监测系统是我国最早建立的特大型桥梁结构安全监测系统。由于设计施工上的缺陷,系统运行不久就出现数据采集系统硬件损坏,导致系统处于瘫痪状态。因此联合相关科研单位对损坏的硬件系统进行改造,调整了传感器系统,增加了部分监测内容。笔者对改造后系统的硬件以及监测内容进行了分析,也为以后特大型桥梁结构健康监测系统设计提供了借鉴。

Reconstruction of the Health Monitoring System of Long-Span Bridge

The health monitoring system of Jiangyin Bridge is the earliest structure safety and monitoring system for super-large bridge in China.Because of the design and construction defects,the system hardware of data acquisition was damaged not long time after the system setting up and lead to the system stop working.The damaged hardware of the system was repaired,the sensor system was adjusted and added some monitoring content under the related scientific parties.The author analyzed the system hardware and monitoring content after the system repaired,and also provide the reference for the later design of health monitoring system for super-large bridge.
