Self-Weight Consolidation Prediction Method Considering Properties of Segregating Sedimentation



Harbor areas are constructed on reclaimed ground that uses soft dredged soil for many reasons, and there are numerous engineering problems observed during the ground reclamation. The most critical problem involves the settlement caused by the recurring consolidation of dredged soil over a long period of time. Therefore, research is needed to define the characteristics of the reclamation’s consolidation. In many cases, the existing research results on the behavior of reclaimed ground constructed with coarse soil differ from its actual behavior. Therefore, a predictive study is required to estimate the behavior of dredged and reclaimed ground regardless of the properties of the dredged ground. Accordingly, this study performed the sedimentation and self-weight consolidation test to investigate the impact of the initial water content and input height on the sedimentation and self-weight consolidation properties of nonplastic dredged soil. Then, an estimation method was suggested to calculate the volume after the self-weight consolidation of dredged coarse soil.
