Abstract
The ground surface of reclaimed land with dredged clay settles due to self-weight consolidation for a long term. If the ground surface settles rapidly, the settled space can receive additional dredged clays. In this paper, the ground improvement project with vertical drains for such a disposal pond is introduced. The determination of model ground using the reclamation analysis is a key point because the ground condition at the installation of plastic board drain is not different from that at the design of ground improvement. The adequacy of proposed method is confirmed in comparison with the measured excess pore water pressure distributions at the installation of vertical drains.
