摘要
近年来,桥梁运营阶段的安全问题逐渐凸显,基于现代传感、通信、大数据分析等信息技术的桥梁在线监测与预警系统是对传统桥梁运维模式的有效补充。不同于传统单体桥梁健康监测系统,针对数量大、分布广的常规结构体系桥梁,开发了一套基于安全预警和养护策略的区域桥梁群监测系统。同时探讨了监测系统的架构设计,研究了桥梁遴选、监测参数确定、传感器布设、监测数据处理及预警、预防性养护策略研究等关键问题。在上海某区的实践不仅为保障该区桥梁安全提供有效支持,也为相关研究提供借鉴。
In recent years,safety issues in the bridge operation phase have gradually become prominent.The bridge online monitoring and early warning system which is based on modern sensing,communication,big data analysis technologies have gradually become an effective supplement to traditional bridge maintenance operation.Different from the traditional single bridge health monitoring system,this article proposes the use of bridge group monitoring methods for integrated management of bridges in the region which contains many conventional bridges.This article also discusses the architecture design of the monitoring system,and studies key issues such as bridge selection,determination of monitoring parameters,sensor placement,monitoring data processing and warning,preventive maintenance strategy.The practice in a certain area of Shanghai not only provides effective support for ensuring the safety of bridges in this area,but also provides reference for related research.
