For the doctorate, the Deltares laboratory carried out a series of experiments, reported in Van Eekelen et al., 2012a. Based on this, Van Eekelen developed the new Concentric Arches - design model for the basal reinforcement of the piled embankment (Van Eekelen et al., 2012b, Van Eekelen et al., 2013). This model was validated with measurements from seven full-scale projects and four series of scaled model experiments (Van Eekelen et al., 2015). The calculated results are almost a perfect match with the measured results.
The Concentric Arches model. The loads are transported along the hemispheres and the 2D arches, towards the piles, the geosynthetic reinforcement and the subsoil. This model is available in excel: excel file with Concentric Arches model.
