Parameter Estimation and Numerical Analysis of Self-Weight Consolidation of Slurried Marine Clay

摘要

The self-weight consolidation characteristics of slurried marine clay with high water contents were investigated. Numerical analysis of self-weight consolidation was also performed using the consolidation equation considering the effect of clay self-weight derived by Mikasa (1963). The volume ratio (f) and effective stress (p) relationship, and the hydraulic conductivity (k) and volume ratio (f) relationship are needed as parameters for numerical analysis. The f-p relationship was determined by a centrifugal model test using a small centrifuge by two methods, and the k-f relationship was determined by the centrifugal model test and standard oedometer test. The validity of these parameters was then investigated in comparison with the measured and calculated settlements.
