PEBSTER (1×1 m): strains and displacements in piled embankment with a steel mesh
The research was part of the H2020 funded “GEOLAB, Science for Enhancing Europe’s Critical Infrastructure”. The PEBSTER project focused on load transfer in piled embankments with steel reinforcement. In the first stage, the 1.1 x 1.1 m lab test was investigated using DFOS strain fibres, EpsilonSensors and 3DSensors grids. The analysis based on thousands of sensing points allowed a detailed assessment of the spatial deformation of the embankment (both strains and displacements).

Project challenges
Benefits of using the DFOS monitoring system
Results of using the DFOS monitoring system
Deformation of the embankment was determined by the presence of the stiffer columns. Their influence is visible both on the distributed strain and displacement profiles, as shown below. Thanks to the DFOS-based monitoring system, the internal performance of the embankment could be precisely measured.
