摘　　要：本文在对原系统分析研究的基础上，结合江阴大桥升级改造工程实际，对升级改造的系统构成、监测技术的应用、子系统的设计等方面进行了研究。提出了江阴大桥结构健康监测系统的升级改造的总体要求与思路，明确了升级改造的主要内容。从传感器的布置、数据采集的要求、传感器的技术参数等方面对各个子系统进行了工程设计。针对系统升级改造的总体目标与要求，对江阴大桥结构健康监测系统的系统软件和数据处理进行设计研究。就如何应用监测系统的数据建立运营情况下的江阴大桥评估系统进行了研究，从结构异常状态预警、结构状态识别、结构健康状态评估方法方面进行了设计分析。On the basis of analytical investigation for the original SHM system, the constitution of upgraded system, application of monitoring techniques and design of subsystems were studied in combination with the upgrading and modifying project for the Jiangyin Bridge. Total requirements and considerations were proposed for the upgrading and modifying project, and the chief items to upgrade the SHM system were determined. Then, engineering designs were created for each subsystem based on transducer arrangement, requirement for data acquisition and technical parameter of transducer etc, Aimed at the total requirements and considerations of the upgrading and modifying project, the system software and data treatment manner were investigated for the SHM system of the Jiangyin Bridge. It was investigated how to establish the evaluation system of the Jiangyin Bridge in service condition by application of monitored data from its SHM system. The issues including abnormal structural state prewarning , structural status identification and structural health condition evaluation etc were studied.
