Concrete core and mega braced tube system is adopted to resist wind load and earthquake action. The high-rise building lies in the soft soil area and high density seismic zone. The aspect ratio is 9.0 and the maximum axial force in the mega column is about 1 000MN. The pile is of 75m length and the raft is of 6.5m thickness. These characteristics of the building bring challenges to the foundation design. The main technical issues on the foundation design, such as pile options, analysis on the settlement and moment of raft, as well as the detail of mega column-base, were introduced. In addition, the views were also presented including buried depth, fixing location and punch capacity of raft.Keywords: buried depth of the foundation; fixing location; raft foundation; punch capacity; detail of mega column-base; constructability作者簡介：周建龍，教授級高工，Email：jianlong_zhou@ecadi.com。參考文獻［1］ ARUP，華東建筑設(shè)計研究院有限公司.高銀117大廈超限設(shè)計專家審查報告［R］.2010, 4.［2］ JGJ 3—2010高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］. 北京：中國建筑工業(yè)出版社，2011.［3］ GB 50010—2010混凝土結(jié)構(gòu)設(shè)計規(guī)范［S］. 北京：中國建筑工業(yè)出版社，2010.［4］ 包聯(lián)進，姜文偉，孫戰(zhàn)金.
