Doctorate study Basal Reinforced Piled Embankments
...
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. Suzanne van Eekelen received several awards for her work on basal-reinforced piled embankments.
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.

A piled embankment consists of a foundation on piles, with on top of that an embankment. The bottom section of the embankment is composed of a granular material and reinforced with one or more geosynthetic layers. The embankment can be raised with sand or granular material. The piled embankment is finished with a road or a railroad construction.
Within the granular layer, a kind of arch occurs. The load is transferred along these arches. This phenomenon is called arching.
