Abstract: 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.

Key words: Spring-fiber, Tailings dam, Deformation, Monitoring
