Abstract

This study aims for a software tool that predict secondary settlements in soft layers on which secondary dikes are founded based on cone penetration test data. In the literature study five equations have been found that relate cone resistance and friction ratio to volumetric weight and over consolidation ratio. With the volumetric weight and over consolidation ratio the NEN-Bjerrum settlement parameters can be determined and with that the strain for a layer. After this study the focus lies on developing a software tool and the resulting output. In the end it seems, qualitatively, that the results are not useful in engineering practise because the resulting settlements are unexpectedly large.
