Abstract:Through the design of foundation treatment of a high-rise residential district in Jining, the design process of CFG pile composite foundation was introduced in detail, including economy analysis, calculation of bearing capacity and deformation, and construction and detection. The settlement observation results and calculation results were analyzed and compared, and the feasibility of using CFG pile composite foundation in high-rise building was demonstrated.

Keywords:high-rise building; CFG composite foundation;  settlement observation
