随着我国轨道交通的迅速发展,地铁隧道工程的安全状态监测也成为了研究热点,阐述了一种利用区别于点式测量的方法,即高精度长标距光纤布拉格光栅传感器,其具有布设方便,抗干扰能力强,耐腐蚀性等优势,并详细介绍了长标距光纤传感器在佛山市地铁盾构隧道中的监测内容和应用情况。
With the rapid development of rail transit in our country, the monitoring of the safety status of metro tunnel project has also become a research hotspot, and a method of using the difference from spot measurement is described, that is, a high-precision long gauge fiber Bragg grating sensor with convenient layout , Strong anti-interference ability, corrosion resistance and other advantages, and introduced in detail the long-range optical fiber sensor in the monitoring of subway tunnels in Foshan content and application.
