Abstract: Based on the successful design experience of Jinmao Building and Shanghai World Financial Center, this paper attempts to analyze and evaluate the behavior of piled raft foundation for Shanghai Center Tower from the design perspective. The weight of the building, buoyancy of the water and load-sharing between pile and soil are analogously analyzed. Capacity of pile, load on pile group, thickness and bending moment of raft, settlement of piled raft are calculated and analyzed especially. The analysis thinking, methods and results can be served as references for design and study of piled raft foundation for super-tall buildings.

Key words: superhigh building, piled raft foundation, safty
