One of the methods for increasing the capacity of disposal pond for dredged marine clay is the volume reduction in already reclaimed dredged clay ground. In the vacuum consolidation method, the pore water in the reclaimed clay ground is squeezed by vacuum pumps, and ground surface settles. In this paper, the performance of reclaimed land with dredged clay by the vacuum consolidation method is introduced, and is compared with the prediction of consolidation behavior at the design. In addition, the back analysis of settlement behavior of such reclaimed ground is performed, and the design procedure of vacuum consolidation for reclaimed ground with dredged clays is proposed.
