The design of the compound pile foundation of the Shanghai Middle School Gymnasium is introduced. According to the characteristics of this kind of independent compound pile foundation and the special settlement control requirement of the upper structures, an appropriate and simplified method is adopted in design. At the same time, the cooperation of upper structures and foundation is considered in the calculation of settlement of compound pile foundation so that the result would be more accurate.
