【摘要】：桥梁建成以后,由于受到气候、环境因素的影响,结构材料会被腐蚀和逐渐老化,长期的动静载作用,其强度和刚度随着时间的增加而降低。这不仅会影响行车安全,也会使桥梁的使用寿命缩短。桥梁结构健康监测是对桥梁结构及其工作环境进行实时监测,并利用监测数据分析大桥的健康状况、评价大桥的承受静动载的能力和结构的安全可靠性,为运营养护提供决策依据。本文研究的项目为上海巨一科技发展有限公司为上海松江地区新建的一座跨黄浦江的大桥的结构健康监测系统的设计开发项目,同时本项目也是上海市桥梁大数据研究的课题之一,本人为该项目的项目经理,负责该项目的设计、开发、实施以及后期运营维护工作。本文主要的工作内容为依据据项目需求,开发一套能满足辰塔公路跨黄浦江大桥的结构健康监测系统,通过在桥梁结构重要截面位置安装获能取代表桥梁环境、荷载及结构响应信息的传感器设备,结合定期人工巡检的检测数据,监测桥梁可能存在的状态改变,尽早发现结构损伤,并对桥梁结构的改变及损伤进行评估,提出调整、维修或管理建议。根据相关要求我们结合以往系统的开发经验和国内外同行的经验教训,通过对桥梁的环境特点、结构特点及软件系统功能性需求进行分析,首先进行了系统的总体设计,完成了桥梁监测点的布置及相关监测参数的确定,传感器、采集设备、通讯设备、存储数据处理等设备的设计、选型、采购、安装调试工作；在系统软件上完成了对数据自动采集软件、人工巡检养护软件、综合预警安全评估软件、用户界面软件、中心数据库软件几个子系统分别进行了设计、开发和调试工作。辰塔公路跨黄浦江大桥结构健康监测系统的建成运营,标志着代表具有最新技术的第三代桥梁结构监测系统的设计开发成功并投入桥梁结构监测的实际运用中,具有重大的科研和应用价值。
[Abstract]:After the bridge is completed, due to the influence of climate and environmental factors, the structural material can be corroded and gradually aged, and the long-term static and static loading function, its strength and rigidity decrease with the increase of time. This will not only affect driving safety, but also shorten the service life of the bridge. The bridge structure health monitoring is to carry out real-time monitoring on the bridge structure and its working environment, and utilize the monitoring data analysis bridge's health condition, evaluate the capacity of the bridge to withstand the static load and the safety and reliability of the structure, and provide decision basis for the operation and maintenance. The project is a design and development project of Shanghai Giant Science and Technology Development Co., Ltd. to build a new construction health monitoring system across the Huangpu River, which is a new bridge across the Huangpu River in Shanghai. At the same time, this project is also one of the subjects of the research on bridge data in Shanghai. I am the project manager of the project, who is responsible for the design, development, implementation and post-operation maintenance of the project. The main contents of this paper are to develop a structure health monitoring system which can meet the crossing of the Huangpu River Bridge in ChenTower Highway according to the project requirements, and adopt sensor equipment which can take representative of bridge environment, load and structural response information at the important section position of the bridge structure. Combined with the detection data of periodic manual inspection, monitoring the possible state change of the bridge, finding the structural damage as early as possible, and evaluating the change and damage of the bridge structure, and proposing adjustment, maintenance or management suggestions. According to the relevant requirements, we combine the development experience of the past system and the experiences and lessons of the domestic and foreign peers, and through the analysis of the environmental characteristics, structural characteristics and functional requirements of the software system, the overall design of the system is firstly carried out. The layout of bridge monitoring points and the determination of relevant monitoring parameters, sensors, acquisition equipment, communication equipment, storage data processing and other equipment shall be designed, selected, purchased and installed and debugged; the software for automatic data acquisition and manual inspection and maintenance shall be completed on the system software. The design, development and debugging of integrated early warning safety assessment software, user interface software and central database software are respectively carried out. The completion and operation of the health monitoring system across the Huangpu River Bridge in ChenTower Highway indicates that the design and development of the third generation bridge structure monitoring system with the latest technology is successful and put into the practical application of bridge structure monitoring, and has great scientific research and application value.
