Abstract
In this study consolidation properties of marine clay in south Korea were investigated through standard consolidation tests (SCT) and constant rates of strain (CRS) tests, and Rowe Cell tests. This examination was conducted based on the field data collected in Kwangyang Bay area, which is one of the representative harbor regions in the southern coast of Korea. Consolidation parameters, including preconsolidation pressure (P c ), compression index (C c ), swelling index (C s ), overconsolidation ratio (OCR), vertical and horizontal consolidation coefficient (C v , C h ), vertical and horizontal coefficients of permeability (K v , K h ), were obtained through the statistical analysis. A correlation between these parameters was evaluated by the regression analysis after removing outliers of the collected data. As a result, it was shown that the relationship between swelling index and compression index was C s = 0.0969C c and between modified compression index and compression index was C c ′ = 1.1411C c(lab). Furthermore, the mean consolidation coefficient ratio (C h /C v ) and permeability coefficient ratio (K h /K v ) were found to be 2.34 and 2.21, respectively.
