ABSTRACT: Suction caisson can be an effective form of foundations for offshore structures. In relation to an offshore/near shore project, some physical model tests were carried out to study the behaviour of suction caissons during installation. The full instrumented model allowed displacements of the suction caissons and soil plugs and deformation of the adjacent soil to be measured. The suction effect on the soil inside and surrounding the caisson were evaluated. The testing results indicate that soil plugs were sizable in suction installation. The ground surface surrounding the caisson settled during suction installation. The influences of the dimensions of caissons, the wall thickness and the properties of the soil on the penetration depth and the penetration resistance are also discussed.
