Abstract :

In dredging and reclamation, self-weight consolidation of marine clay need relatively long time. In this study, to accelerate self-weight consolidation time laboratory large size column test were performed using prefabricated vertical drain board. And also presented optimum time of prefabricated vertical drain board insert. Prefabricated vertical drain board-test result showed l/2 time to consolidation compared to Selfweight consolidation-test. Therefore, It can be judged that in reclamation of dredged marine clay, prefabricated vertical drain board can used to accelerate self-weight consolidation.
