Abstract

In this study, an experimental research on the acceleration effect of dredged soil's self weight consolidation with seepage consolidation and PBD was conducted. The middle-sized consolidation equipment had been manufactured in order to investigate the acceleration of sedimentation and self-weight consolidation by PBD and a lower drainage. Seepage pressure was applied to the PBD installed in the center of the test equipment and a drainage by seepage pressure was allowed. The comparison between cases with and without PBD and seepage pressure reveals that the quantity of drained water and the amount of settlement was nearly 1.2 times to 3.68 times greater in the case with PBD and seepage. Early consolidation completion and the use of reclaimed site are expected due to the acceleration of settlement and increase of the quantity of reclamation if PBD is installed while being reclaiming using the result of the research.
