To predict the settlement of reclaimed land by dredged clay, the consolidation parameters coverign a wide stress range are necessary. A determination method of consolidation parameters from small to middle stress range for clay sediments is proposed by means of centrifuge self-weight consolidation coupled with back analyses. T he applicability and the accuracy of the method are confirmed as far as the centrifuge test is carried out until the end of primary consolidation (EOP). To further reduce the experiment time, an alternate procedure in which the centrifuge run is terminated before the EOP is proposed and found promising.
