Dredger fill with high moisture content,has disadvtanges of low strength,high compression,and underconsolidation.It is unsatisfactorily reinforced by strong tamping and consolidation with filler.Relying on Daxiaodeng land creation project in Xiamen,we apply different parameters of vibro-compaction to the reinforcement of artificial dredger fill sandy soil foundation,such as vibration frequency,vibration mode and construction method,and determine the frequency parameter and vibration mode suitable for dredger fill sandy soil foundation.The results show that dredger fill sandy soil foundation is effectively reinforced by vibro-compaction method.After the construction treatment,the bearing capacity of the foundation and the standard penetration hit number are improved.After being worked,the foundation has a bearing capacity of 150 kPa,and the standard penetration hit number for about half of test area exceed 30,which meets the standard for subsequent construction.The soil reaches medium density state.It proves that the vibro-compacting method is suitable for the reinforcement of dredger fill sandy soil foundation.The method can reduce the construction consumption,and improve the economy and benefit.
