摘要 介绍了一种可移动式柔性铠装套管封装FBG(Fiber Bragg Grating)传感器,用于物体表面曲率测试,通过移动传感器管道内FBG,实现道路结构层纵向形状及变化监测,测试理论可以用来监测多层介质道路结构的车辙及路基沉降,并利用理论与试验方法建立了波长变量和曲率之间的关系式,分析了结果产生误差的原因。 This paper introduced a mobile flexible armored casing package FBG（Fiber Bragg Grating） sensor, to objects surface curvature test, by moving the sensor inner pipeline FBG, realized the road structural layer longitudinal shape and change monitoring, the testing theory could be used to monitor the track and roadbed settlement of multi layer dielectric road structure, and established the relation of wavelength variables and curvature using theoretical and experimental methods, analyzed the errors reasons.
