Abstract: In recent years, Chinese engineers and researchers have proposed many new technologies and theories in the field of foundation engineering. The importance of forming condition of composite foundation, the position of composite foundation in foundation engineering, the contribution of composite foundation theory to the development of foundation engineering theory were analyzed and discussed, as well as composite pile foundation, the relationship between composite pile foundation and composite foundation. A new technique for setting piles in foundation namely pile implantation technique, the design theory based on deformation control in geotechnical engineering were also involved. 

Keywords:foundation engineering； composite foundation； composite pile foundation； pile planting technique； design theory based on deformation control
