Abstract

The optical fiber sensing methods have been utilized for observation of ground deformation. In this study, performance of a new PE-Pipe optical fiber sensor, developed to increase sensing accuracy, was verified. Firstly, a heat fusion method to connect optical fibers to PE-pipe surface firmly was developed. Next, measurement sensitivity of the PE-pipe optical fiber sensor was verified by comparing pipe strains obtained by strain gages and those by optical fibers through PE-pipe bending experiment. Finally, it is ensured that the PE-pipe optical fiber sensor is applicable for investigation of small range ground deformation through an uneven ground settlement experiment for the PE-pipe sensor.
