摘要
光纤传感器作为一种线性的测试仪器,应用于岩土工程领域时,较传统传感器有更多的优越性和更加广泛的应用前景。介绍了光纤Bragg传感器的工作原理及应用,并通过混凝土试件的加载试验,对FBG应变传感器和电阻应变计量测混凝土的应变测量进行了比较。提出准分布式光纤光栅传感器在现场应用及实验室中将得到更加广泛的应用。
As a kind of line form sensor, the fiber optic sensor has more superiority and more extensive applied foreground than the tradition sensor. In this paper, the working principle and the application of fiber Bragg gratings is briefly introduced, and based on the results of the loading experiment to concrete specimens, measurement on concrete strain carried out by FBG strain sensors and resistance strain gauges are compared It is put forward that the quasidistribute fiber-optic sensor will get a more extensive application on both the spot application and the laboratory lieutenant general.
