Outline of Final Research Achievements

In this study, a model of PE-pipe optical fiber sensor on which surface longitudinal optical fibers are installed was produced. And lateral movement test device in which steel springs are installed to express buried condition was used to bent the PE-pipe sensor and strain distribution was obtained. The pipe strain gauged by the optical fiber and strain gauge showed correct agreement. Further, lateral pipe displacement obtained from the pipe strain agreed the displacement data by the wire displacement meter. Furthermore, back analyzed data of input displacement calculated by effect matrix showed good agreement with input displacement.
