Considering the role of foundation slab, the stress and settlement of composite foundation improved by cement soil pile were analyzed by use of 3D finite element method. The results show that the foundation can decrease the settlement of composite foundation, which is helpful for the design and construction of composite foundation.
Keywords:  foundation slab; cement soil pile; stress, settlement
