Distributed sensing in foundation piles during mechanical load testing
The aim of the project was to investigate the behavior of foundation piles during their mechanical load testing. In order to achieve this, three monolithic sensors – EpsilonRebars – were attached to the reinforcing cage of the piles in question. This innovative DFOS-based system allowed for precise and high-quality analysis of the performance of structural components deeply embedded in the soil, what was previously unattainable with conventional techniques.

Results of using the DFOS monitoring system
The graph shows the horizontal displacements of the pile during successive steps of the load test. The displacement was calculated based on the strain changes measured by the EpsilonRebars in known configuration. Thanks to the DFOS approach, measurements were taken with an extraordinary level of spatial resolution, amounting to less than 1 cm.
