摘要：
A new type of composite foundation, named concrete-cored sand-gravel pile composite foundation for thick and soft ground treatment is introduced in this paper. The new style composite foundation is composed of the concrete-cored sand-gravel pile, the soil between piles and the cushion. This paper describes its design and construction technology, and analyzes its load transfer mode and improvement mechanism. Field test results indicate that the new type combined pile is sufficient in satisfying the stability and the post-construction settlement of embankment and foundation.
