Foundation Design for the Shanghai Center Tower

Abstract

This paper describes design process of foundation of Shanghai Center Tower, the China’s tallest building. The foundation system is piled raft founded on deep deposit of delta of Yangtze River. The geotechnical condition and the design progress including the selection of pile type and bearing stratum, pile capacity, raft thickness, foundation settlement will be outlined. The settlement is an important issue in soft soil area for super-tall building, and the optimized design of pile foundation stiffness to reduce differential settlement is also presented in this paper.
