Dutch Research on Basal Reinforced Piled Embankments
Several long-term field studies, an extensive series of laboratory tests and finite element analysis are being carried out with the aim of further optimising the Dutch CUR 226 design guideline for piled embankments. It has been found that the strains measured in the geosynthetic reinforcement (GR) in the field are smaller than the strains predicted with Zaeske's design model, which was the model adopted in the CUR 226. Two modifications are suggested to Zaeske's load deflection behaviour for geosynthetic reinforcement: changing Zaeske's triangular load distribution on the GR strip to an inverse triangular load distribution, and taking into account the entire area below the GR, rather than only the area between the adjacent piles. Adopting these two modifications leads to a reduction of 43-66% in GR strain in the case of the model experiments, and therefore to a reduction of 43-66% in the required GR strength.
