【Abstract】 This paper is concentrated on the experiment on the performance of vibrating wire sensors and FBG sensors which are placed in a concrete beam. The experimental results demonstrate that FBG sensors is prior to vibrating wire sensors. Based on the application of FBG sensing technology in bridge monitoring ,this article also discusses the major problems faced in a project and realization approachs.更多还原
