摘　　要：沪通长江大桥为超千米级的公铁两用特大桥,结合大桥结构特点及运营养护需求,设计研究了健康监测系统。大桥健康监测系统主要针对主航道桥及专用航道桥,该两桥分别布置监测点292个和109个。监测系统采用车-线-桥-环境综合监测模式,全面反映大桥的结构状况及行车状态。监测系统包括数据采集与传输子系统、数据存储及管理子系统、综合报警与评估子系统及用户界面子系统。为提高监测系统的实用性,以现场养护人员易用为目标,研究了大量监测数据快速识别、修正与分析处理的方法,通过综合报警与评估的方式评判结构状态,进而为养护工作提供科学依据。通过与BIM管理系统相结合,实现大桥全寿命期的信息共享与利用,促进桥梁运营维护模式向"预见修"的方向发展。Th e Hu to n g Ch angjiang R iv er Bridge is a rai l-cum- ro ad b r id g e wi th th e main span 〇 - ver 1 000 m. In the l ight of the st ructural characterist ics and the operat ion and maintenance need of the bridge, the st ructural heal th moni tor ing system for the bridge, mainly for the main ship chan-nel and the special ship channel br idges of the bridge, has been researched and designed and on the two ship channel bridges, total ly 292 and 109 moni tor ing points are respect ively laid out. In the moni tor ing system, the comprehensive moni tor ing mode of the vehicle- line-bridge-ambience is ap-plied and the moni tor ing system can ref lect all-sidedly the st ructural condit ions and vehicle t ravel -ling condit ions of the bridge. The system comprises the data acquisi t ion and t ransmission subsys-tem, the data storage and management subsystem, the comprehensive alarming and evaluation subsystem as well as the user inter face subsystem. To improve the pract icabi l i ty of the system, the easy usage of the system by the site maintenance personnel is taken as the goal and the methods of the rapid ident if icat ion, cor rect ion, analysis and processing of a great amount of the moni tor ing da-ta have also been researched. The st ructural condit ions of the br idge are judged by the compre hensive alarming and evaluation and the scientific bases for the maintenance at the site are henceprovided. By way of integrat ing the system wi th the BIM system, the informat ion shar ing and ap-plying of the life cycle of the bridge is realized and the operat ion and maintenance mode of the bridge is pushed towards the development of the predictable rehabi l i tation＂.
