|
摘要
基于光纤Bragg光栅传感技术,对洛阳瀛洲大桥结构健康监测系统进行了研究。介绍了瀛洲大桥健康监测系统的组成和各系统的功能,提出了基于FBG传感技术的长期监测与周期检测结合的监测策略,根据大桥构件在结构安全中的重要性和易损性确定了监测内容,重点对于大桥关键受力区-拱脚倒三角区进行了有限元分析,在此基础上进行了FBG传感布置。最后对于大桥运营结构预警与评估实施方法等进行了探讨。
Based on fiber bragg grating sensing technology,Luoyang Yingzhou Bridge structural health monitoring system is studied.The composition and the function of the structural health monitoring system for the Yingzhou Bridge are introduced and strategy based on FBG sensing technology of long-term monitoring and detection of the cycle monitoring are proposed.According to the structural safety of the bridge component of the importance and vulnerability, the content of monitoring was determined,focusing on the analysis of the key bridge force-arch foot inverted triangle area with the finite element method.Based on the review,the placement of FBG sensor is presented.Finally,the structure of the bridge operator early warning and assessment of the implement methods were discussed.
