3D Experiments in bath: groundwater in geosynthetic-reinforced pile-supported embankments
This paper presents small-scale 3D experiments that investigate how groundwater affects the behaviour of geosynthetic-reinforced pile-supported (GRPS) embankments. To conduct these experiments, an existing test set-up was submerged in a bath.
The experiments showed that groundwater reduces the load that is exerted on the piles. This is primarily due to Archimedes uplift forces, rather than a change in soil arching. The pile loading quickly recovers when the groundwater level decreases again. No significant correlation between groundwater level and geosynthetic reinforcement strains was observed.
