Abstract

[Basing on the foundation treatment project of the beach area of Baosteel and considering the effect of dredger fill and miscellaneous fill on the consolidation behavior, the whole consolidation process of the foundation was studied with Plaxis program, and the results were validated by the monitor data. It is concluded that the excess pore pressure (EPP) of the underlying soft soil has not been dissipated completely before the foundation treatment, so the negative EPP value is caused in the following monitoring. Early settlement is mainly composed of the transient settlement due to the poor permeability of the foundation. In addition, early settlement is mainly consisted of the upper dredger fill, and there is an apparent deformation in the underlying stratum after inserting PVDs and preloading. The results are significant not only for understanding the consolidation history of new dredger fill foundation, but also for post-processing and monitoring work.]
