弹簧式光纤应用于尾矿坝内部变形监测的研究

Research on Internal Deformation Monitoring of Tailings Dam by Spring-fiber

研究了基于光时域反射技术的弹簧式光纤传感器。通过传感器设计试验,分析得出弹簧式光纤传感器的变形监测公式,并通过结构变形监测的应用试验,验证弹簧式光纤变形监测公式的准确性,为将弹簧式光纤传感器用于尾矿库变形监测提供参考。

An spring-fiber sensor based on optical time domain reflectometry was studyed in this paper. A formula about the deformation monitoring of spring-fiber sensor was obtained through the analysis of sensor design experiments. And through the application test of structural monitoring deformation, a correction of the formula was advanced, And it provided a reference of internal deformation monitoring in tailings dam by spring-fiber.
