Stone columns are used in practice for ground improvement of soft subsoil. Current design procedures of these columns are based on simple empirical calculations. This research project investigates the behavior of a base reinforced embankment constructed on a soft clay layer, which is improved with stone columns. Centrifuge tests were performed in order to gain a deeper understanding of the interaction problem within the structure. Stone columns were constructed in-flight using a newly developed installation tool. First analysis of test data shows a significant change in stress state due to column construction and the influence on the clay behavior.
