PREDICTION AND ASSESSMENT OF RECLAMATION BY DREDGED MARINE CLAY

Abstract

In the construction of NEW-KITAKYUSHU airport, the reclamation by dredged marine clay was performed. In this paper, the predictions at several stages on the reclamation and the effectiveness of modification of prediction with the monitoring are described. The modification is the determination of consolidation parameters so as to fit the calculated change of elevation as well as the distributions of water contents and excess pore pressure with the monitoring data. Use of the best-fit consolidation parameters improves the precision of prediction. The best-fit consolidation parameters are located in the range of consolidation parameters measured on the samples taken from the reclaimed land.
