Abstract
For conventional gravity type offshore structures constructed on the soft ground, which is located on the western and/or southern Korea, the excessive consolidation settlements are caused by the self-weight of the structures and so additional ground treatment methods are generally needed. Several types of improved foundation systems utilizing buoyancy applicable to even the soft ground were introduced for economical and efficient design of the offshore structure. In this study, a series of numerical simulations on the consolidation and lateral behaviors of breakwaters with the improved foundation systems utilizing buoyancy were carried out. From the results of numerical simulations it is found that the foundation systems utilizing buoyancy are efficient for reducing the maximum consolidation settlements without reducing lateral safety.
