光纤Bragg光栅传感器在桥梁监测中的应用
|
摘要
论述了采用布拉格光栅对应变进行传感的理论和方法,得出了布拉格中心波长与应变之间的理论关系式,并实际监测了宁波市招宝山大桥在车辆载荷下的应变.监测结果表明:光纤Bragg光栅可以方便地监测大桥的疲劳损伤,为桥梁结构的健康诊断提供了相应的依据.
The theory and methods of strain sensing for bridge using FBGS is proposed, and the theoretical relationship between the wavelength of FBGS and strain is also obtained. The theory has been applied to monitoring the process of strain variation of Zhaobaoshan Bridge under traffic load. The results indicate that FBGs can handily measure in bridge’s fatigue damage monitoring with satisfying accuracy. This finding is believed to facilitate bridge’s structural health diagnosis.oring
