Abstract: According to Shanghai harbor ground treatment project, considering the engineering properties of fine sands and disturbed soft soils underlying it, method of PVD-improved subsoil with two technologies of vibroflotation compaction without additional stone aggregates for improving fine sands as well as well dewatering combining with dynamic consolidation for strengthening the disturbed soft soils underlying the hydraulic fine sands is introduced. Based on results of field tests, large-area vibroflotation compaction construction parameters are determined; and the increasing and dissipation regularity of excess pore water pressure in different soil layers and its influencing factors are analysed. Finally, some useful conclusions are drawn.

Key words: dynamic consolidation, hydraulic fine sands, vacuum well dewatering, vibroflotation without additional backfill materials, ground treatment
