| According to the field measurement of dredging-reclaimed land, the actual self-weight consolidation settlement has been frequently reported to be less than the predicted values based on the laboratory tests results. The author estimates that one of the reasons is the reduction of the compressibility due to the sedimentation of the dredging material, Furthemore, the aging effect is ignored in the consolidation characteristics of the very low stress range as a pump dredging-reclaimed land. In this paper, a series of seepage consotidation tests has been carried out by applying the seepage force to the specimen prepared by sedimentation in consolidmeter in order to clarflfy the aging-effect on the compressibility of dredging clayey soil, Also, with a view to overcome unstable consolidation solution occurring in the case where the initial water content is higher as pumpdredging reclaimed land, the finite difference analysis technique using predictorforrector method is suggested that it gets good agreement with ezperimental results. Finally, the compressibility of the dredging clayey soil is depended on self-weight consolidation time. |
