Abstract

A construction method that combines plastic board drains (PBD) to a construction method that promotes the self-weight consolidation phenomenon of reclaimed soil from dredged clay by dropping the water pressure of the soil base was put to practical use, showing tremendous results. A numerical simulation postulating this construction method was performed using a soil-water coupled finite deformation analysis in this study, demonstrating the accelerated effect of self-weight consolidation through this construction method. In addition, we studied the effect of dewatering and drain pitch, as well as the effect of clay soil thickness, demonstrating the characteristics possessed by this construction method. We also demonstrated that clay with ultra-high water content soil such as dredged clay can cover soil-water coupled finite deformation analysis through these analyses.
