The design of foundation of a tall building is described, which fully analyses the on-site soils characteristics and the structural features of the main building. In the design,the authors make good use of favorable condition and evade unfavorable elements as well as aclopt special methods. Only a few balance settlement piles are applied to overcome the excessive differential settlement caused by complex foundation and uneven loads of superstructure.The design results in good effects.
