Self-weight Consolidation Analysis of Rapid Deposited Ground

This paper reviews depositional environments, consolidation characteristic of marine deposits along the Nam-Yang river mouth and then analytical solution of self-weight consolidation is made to find consolidated state. This area has been deposited through the short geological age(22year). It's deposition rate is as high as 70cm/year and the height of deposition may be $3{\sim}12m$. It's known that this area is in the under-consolidated state from OCR and analytical solution. It is conclude that the under-consolidated state should be considered in prediction of consolidation settlement.
