Long-term Settlement of the Reclaimed Quasi-overconsolidated Clay Deposits

Structures are frequently built on a dredged clay layer overlaid by a soft marine clay deposit in coastal areas of Korea. Large consolidation settlement usually occurs in the case and this may cause damages of super-structures. So, the evaluation of long-term consolidation settlement is very important in design and construction. Therefore, in this study, a long-term consolidation characteristics of marine dredged clays are investigated. Firstly, the relationship of on marine dredged clays near Gwang-yang Port was evaluated. Secondly, long-term consolidation characteristics of the pseudo-preconsolidated ground were evaluated.
