Abstract： According to current code, the composite foundation design by optimizing pile foundation stiffness to reduce differential settlement was discussed. Calculating settlement method of composite pile foundation was applied to composite foundation to considering the influence of the pile site or pile stiffness distribution. A new method was provided to locate pile in rigid pile composite foundation design. 

Keywords： rigid pile composite foundation; optimized design of pile foundation stiffness to reduce differential settlement; settlement calculating
