Abstract:The design method of CFG pile composite foundation under independent foundation was analyzed and four practical design methods of CFG pile composite foundation under independent foundation were given. The methods of calculating bending moment of foundation plate and checking foundation height according to punching and cutting were introduced when CFG pile composite foundation was adopted under independent foundation. The specific examples were provided. 

Keywords:CFG pile composite foundation; independent foundation; design method
