摘要
根据应用对象的不同,从应变传感和温度传感两个角度出发,主要介绍了隧道工程中分布式光纤传感技术和光纤光栅传感技术(FBG)在隧道管片收敛变形、隧道结构纵向沉降或隆起、周边土体位移、围岩变形及稳定性、隧道火灾报警等方面的应用,对具体应用中的光纤布设工艺作了简要介绍。同时讨论光纤传感技术在应用中存在的问题,并展望了该技术在隧道工程上的应用前景。
According to different application object,the article from two angles of strain and temperature sensing,mainly introduces the application of the distributed optical fiber sensing technology and fiber bragg grating sensing technology(FBG) in the convergent deformation of tunnel tube sheet,vertical subsidence or uplift of tunnel structure,displacement of surrounding soil,the deformation and stability of surrounding rock,tunnel fire alarm and soon in tunnel engineering,besides the specific application of optical fiber laying process is introduced. At the same time,the problems existing in the application of fiber sensing technology are discussed,and the application prospect of the technology in tunnel engineering is prospected.
