Abstract

The new style composite foundation is composed of the concrete-cored sand-gravel pile, the soil between piles and the cushion. According the work condition under the embankment, and considering the annular drainage section of sand-gravel columns composite foundation, the control equation and analytical solution of composite foundation was obtained, the average degree of consolidation were given. Finally the comparison between the calculated results and the filed measured data showed that the calculated excess pore water pressure, the degree of consolidation and the settlement-time relationship were consistent with those of field data respectively.
