Abstract

The vacuum consolidation method is one of volume reduction methods for dredged clay ground in disposal ponds. In this paper, the design of vacuum consolidation and monitoring results of reclaimed ground with dredged clay are reported. The determination method for ground model based on the reclamation analysis is proposed. The stopping time of vacuum loading is also evaluated by the comparison with the results of Barron's Equation.
