Abstract
Suction caissons have been used in many offshore projects including mooring anchors, breakwaters, sea walls and foundations for offshore structures. For the suction caissons adopted in deep water, the high hydrostatic pressure will contribu te to the suction pressure to sink the caisson into seabed. When concrete caissons with relative thick walls are used in shallow water, there are several technical issues need to be investigated. Model tests were conducted to study the performance of a suction caisson installed in normal consolidated soil. It is observed from the model tests that the suction pressure used for the installation of caisson cannot be too high, but has to be high enough to sink the caisson into seabed. The performance of the suction caisson after installation is also investigated by bearing capacity and pullout tests. The design methods and applications of the suction caissons in offshore projects proposed in the literature are also summarized.
