在役大型T构桥梁健康监测系统设计

On health-monitoring-system design for an existing large T-shaped rigid frame bridge

桥梁健康监测系统目前已被广泛应用于大型桥梁工程的管理和维护中。本文以324国道乌龙江大桥为工程背景,介绍了在役的大型T构桥梁健康监测系统的总体设计原则、系统构成及其各模块功能,分析了数据采集与传输系统设计的总体思路和框架,并对桥梁安全与预警系统模块设计思路进行了简要的讨论。乌龙江大桥桥梁健康监测系统的实施,对评定该桥的安全运营状态,提高桥梁的管理水平,保证结构的安全性和可靠性,都将发挥重要作用。

Bridge health-monitoring-system（HMS） has been widely applied in the management and maintenance of important bridge engineering.This paper presents the general design principle,system formation and the basic module functions of HMS for an existing large T-shaped rigid frame bridge,based on Wulongjiang bridge in National Route G324.The general considerations and frame of data acquisition and transmission system are investigated,and design consideration for the bridge safety and pre-alarm system module is also briefly discussed.The construction of HMS on Wulongjiang bridge will have significant effect on the enhancement of the management level and the structure safety and reliability.
