In Shanghai

the foundations of three super-tall buildings

88-story Jinmao Tower

101-story Shanghai World Financial Center (SWFC) and 121-story Shanghai Center Tower (SCT)

are compensated piled raft (box) foundations with deep embedment. It is worth discussing how to make use of advantages of compensated foundation during foundation design and to estimate the wind resistance of deep embedment of foundation. Based on the analysis of the interaction of high-rise building and ground foundation

the pile raft foundations of the three buildings are analyzed using the statistical empirical formula. A considerable amount of piles can be saved after analyzing

and their bearing capacities and deformations of the foundations can still meet the design requirements. Meanwhile

the capability of optimizing design is further discussed

and the diaphragm wall is proven to be able to share a considerable amount of load. The re-analysis of the relevant cases puts forward suggestions for further improving the design theory of the deep buried pile raft foundation

which can save a lot of investment for China.
