Abstract: The purpose of this study is to understand characteristics of marine clay in the Busan Region by calculating dynamic and consolidation characteristics of dredging reclamation clay in the region and the relationship among void ratio-effective stress-permeability coefficient through self-weight consolidation based on a centrifugal model test. In the study, a standard consolidation experiment was conducted to calculate Compression index (Cc) and permeability Change index (Ck) for the purpose of understanding consolidation characteristics of the sample at a low void ratio. According to the result of the self-weight consolidation experiment, the representative constitutive equation was e = 2.8σ’-0.142, k = 1.62×10-5 e4.82. Also, the bulking factor calculated by using PSDDF (Primary consolidation, Secondary compression, and Desiccation of Dredged Fill) converged toward 1.083-1.266 at the finish point of self-weight consolidation.
