Abstract
In constructing breakwaters, which have generally been located on a soft ground in Korea recently, considerable expenditure and time consumption are required for a ground improvement. Therefore, a new type of breakwater applicable to soft ground conditions was developed with considerations of economy and stability, and the evaluation on the behavior of the soft ground breakwater has also been investigated. In this study the evaluations on consolidation behavior of the soft ground breakwater proposed herein were performed from the laboratory model test and finite element analysis for various cross-sections of breakwater and ground conditions. And, the applicability of the soft ground breakwater was also examined by comparing with consolidation settlement based on Terzaghi\\\\\\\\'s one dimensional consolidation theory. From the model test and numerical results, it was found that bottom wall is more efficient to reduce the consolidation settlement than the base width due to the decrease in the thickness of the consolidation layer and the increase in the resistance and that Terzaghi\\\\\\\\'s one dimensional consolidation theory can conservatively be adopted with some accuracy if the location of the consolidation loading is assumed as an end of the bottom wall.
