PERFORMANCE AND PREDICTION OF DREDGED CLAY RECLAIMED LAND BY VACUUM CONSOLIDATION METHOD

Abstract

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.
