Abstract

This work presents a study of the mechanical properties of optical fibre sensors based on fibre Bragg gratings for application in the in situ monitoring of displacements in tunnels. Tests were performed on fibres and gratings in both dry and humid environments. The tests encompassed both dynamic fatigue (constant stress rate) in both two-point bend and in tensile loading and static fatigue (constant stress conditions). The results indicate that the fibres and gratings are expected to have a very long lifetime under the likely mechanical and environmental conditions.
