Analysis of Consolidation Reason to the Dry Jet Maxing Mehod and One Relative Project Example

Composite foundation refers to the treated soft soil foundation,part of which has got strengthened or substituted.As one of the soft soil foundation treament methods,dry jet mixing pile plays an im portant role for its low building cost.The concept and consolidation reason of the Dry jet Mixing method are described.The technology of the Dry jet Mixing method also are discussed.One project example is gived,the theory is proved that consolidation method can improve road bed compaction degree and applied completely to the soft land base treatment through the analysis on detecting data.
