Abstract: In order to study the behavior and working properties of piles-cushion-soil interaction of rammed soil-cement pile composite foundation， field loading tests of single pile and composite foundation with single pile, four piles, nine piles in different lengths and area displacement ratio have been carried out. Distribution of the soil contact pressure, the shaft resistance of pile have been measured by installing special measuring gauges. Based on the test results, the failure pattern, the behavior of piles-cushion-soil interaction were analyzed. Distribution of the soil contact pressure, the stress ratio and the load ratio of pile to soil, distribution of the shaft resistance in single pile and pile of composite foundation have been analyzed.

Key words: rammed soil-cement pile composite foundation, cushion, load ratio, load transfer
