Application Study on a Detecting Tube for Deformation Settlement Monitoring for Earth Dike Based onDistributed Optical Fiber Sensors

摘要

A monitoring structure has been designed to detect settlement using a tube with distributed optical fiber sensors inside. The strain of the optical fibers inside the detecting tube was calculated to estimate the settlement degree of earth dam. The Finite Element Method (FEM) analysis of the tube interaction with the earth dam by ANSYS software is applied to find the best installation location of the detecting tube.
