Oosterweel connection - optical fiber monitoring of a 17-meter high reinforced fill structure

As part of the infrastructure works on the Antwerp Ring, a large number of reinforced fill structures have been constructed in recent years. These structures include reinforced fills with gentler slopes as well as those featuring vertical or near-vertical facings. Within the framework of this extensive road infrastructure project, the client Lantis has selected a reinforced fill structure approximately 17 meters high and 160 meters long, with a near-vertical facing for monitoring deformations in the geogrids ensuring its stability. This paper presents the instrumentation of the geogrids using optical fiber technology and the results of measurements conducted over the past three years at the site. The results are analyzed in accordance with design requirements and their projections.
