【摘要】：结构健康监测系统(SHMS)采用新兴的传感技术、先进的数据采集系统和自动分析工具,具有设计、施工及性能验证,荷载评估及预测,桥梁有效运营的荷载条件监测,不可预见的结构问题的识别等作用。制定详细的SHMS设计的最佳时间是在详细的结构设计完成后、项目施工前,为确保有关结构和重要领域最新的知识用于SHMS设计,需要结构设计师协助形成有效的监测计划。为使桥梁施工、运营、维护和设计验证等工作便利化,为主跨3 300m的墨西拿海峡大桥设计了SHMS。该桥的SHMS采用的模块化的系统具有灵活性,可以在项目完成后及使用寿命期间进行更改、补充和完善;光栅光纤传感器将被该桥的SHMS测试,验证其功能和光纤传感器安装的可行性;SHMS采集的数据被输入到管理和控制系统中,给桥梁所有者和使用者提供决策信息。
[Abstract]:The structural health monitoring system (SHMS) adopts new sensing technology, advanced data acquisition system and automatic analysis tools. It has design, construction and performance verification, load assessment and prediction, and load condition monitoring for effective operation of bridges. Recognition of unforeseen structural problems, etc. The best time to make detailed SHMS design is after the detailed structure design is completed and before the construction of the project, to ensure that the latest knowledge about the structure and important fields is used in the SHMS design, the structural designer is required to assist in the formation of an effective monitoring plan. In order to facilitate the construction, operation, maintenance and verification of the bridge, SHMS. was designed for the 3 300m main span of the Messina Strait Bridge. The SHMS of the bridge uses a modular system with flexibility that can be changed, supplemented and perfected after the completion of the project and during its useful life. The grating fiber optic sensor will be tested by the bridge's SHMS. To verify its function and the feasibility of installing optical fiber sensors, the data collected by SHMS are input into the management and control system to provide decision information for bridge owners and users.
