A suction caisson is installed by applying suction inside the caisson to create a downward net force to sink the caisson into soil. However, the applied suction pressure will also result in formation of a soil plug. This is particularly the case when the soil is soft and when the caisson wall is thick. In this paper, the results of several model tests carried out using a 1 m in diameter consolidation tank and 205 mm in diameter concrete caisson are reported to study the installation process of a suction caisson in clay. Different caissons and different soil conditions were used. Thus study show that the caisson wall thickness and the properties of clay are two major factors affecting the formation of soil plug which in turn, affects the installation of suction caisson.
