Distributed Fiber Optic Sensing in Pile Load Tests: Technological Development and Applications
https://orcid.org/http://orcid.org/0000-0002-1312-0410
Piles enable a safe and convenient solution for providing adequate bearing capacity for civil infrastructures, which can be individually customized to changing soil conditions. Fully instrumented piles with advanced monitoring techniques can offer new insights into the bearing capacity and structural integrity of piles in field tests. Recently distributed fiber optic sensing (DFOS) technologies provide a powerful tool for geotechnical monitoring by enabling distributed and automatic strain measurement along fiber optic (FO) cables. This paper presents the DFOS-based pile monitoring system, which helps to quantify and refine each step during pile testing. According to the construction characteristics of precast piles, bored concrete piles and steel piles, various installation methods of FO cables on piles are introduced, respectively. Two case studies are illustrated to show the capability of DFOS in monitoring the performance of axially and horizontally loaded piles.
