초록
In soft ground, consolidation settlement is mainly consider. The primary consolidation settlement which is the time when the excess pore water pressure is completely dispersed and the secondary consolidation settlement which follows. Recently as the depth of consolidation layer increases the consideration of not only the primary consolidation settlement but also of the secondary consolidation settlement becomes a very important element. But up to the present there were only a few in-depth study of the secondary consolidation settlement performed. At present there are a lot of methods available when it comes to the improvement of soft soil. In this study, Preloading Method which is the most commonly used soft soil improvement method locally was used in order to investigate the method for the reduction of secondary consolidation settlement. The objective of this study is to determine the amount of preloading required to reduce secondary consolidation settlement and to determine whether secondary consolidation settlement using standard consolidation test.
