| Abstract: | Based on the field test data of high replacement ratio sand compacted pile in soft clay,we analyzed the characteristics of single sand pile and the consolidation character of soft clay among the piles,and derived the expressions for the stress ratio of pile to clay,the bearing capacity of single pile and the clay among piles,which can be used to calculate the bearing capacity of the composite foundation and the result may serve as a reference for the engineering design. |
