桥梁健康监测系统结合桥梁结构、计算机技术、网络技术、通信技术等多个学科,通过对桥梁结构状态的监测与评估,为桥梁工程在特殊气候、交通条件下或运营状态严重异常时发出预警信号,为桥梁维护、维修与管理决策提供依据和指导.结合英德北江三桥项目设计实例,介绍了健康监测系统的发展现状,系统设计功能、设计目标、系统构成及结构健康评估系统,其中对传感器的选择及测点布置、系统健康状况的评估和状态分析进行了详细说明,最后对健康监测系统的不足进行了说明.%Bridge structure health monitoring system, combined with bridge structure technology, computer technology, network technology, communication technology and other disciplines, through monitoring and evaluation of the bridge structure status, can provide warning signal for bridge project in the special climate, traffic condition or the severe abnormalities of operation state, provide a basis and a guidance for bridge maintenance, repair and management decision-making. Combined with the Yingde North River 3rd Bridge project design, introduces the development status of bridge structure health monitoring system, function of system design, target of system design, system composition and structure assessment system. Introduce the sensor selection and arrangement of measuring points, system health assessment and analysis in detail, and illustrate the inadequacy of the health monitoring system finally.
