摘要
从工程实用角度归纳了光纤光栅传感器相对于其他传统监测仪器的主要优势,阐述了其在隧道结构安全监测中的适宜性。在此基础上结合某公路隧道衬砌结构的薄弱部位和具体条件,设计了现场自动化监测和无线数据通信系统,采用光纤光栅传感器对隧道支护结构的变形和受力状态进行了实时监测实验,结果真实有效地反映了结构物的运行性态,表明光纤光栅传感器在公路隧道结构安全监测中具有良好的实用效果。
The main advantages of fiber Bragg grating（FBG） sensors are summarized relative to the other traditional sensors from the engineering point of view,and its adaptability is described in the structure of highway tunnel.According to the weak parts and actual conditions of concrete lining in a highway tunnel,the automation monitoring and wireless communication system is constructed on site.FBG sensors are applied to real-time deformation and stress monitoring experiment in the supporting structure of tunnel.The achievements reflect the working state of the structure actually and effectively,and fiber Bragg grating sensors have good practical effects in safety monitoring of highway tunnel.
