The rationality of the analyses and calculation results of composite foundation was judged based on relevant literatures, and the adopted rigid pile composite foundation scheme of the project fulfill the requirements of safety, economy and environmental protection. Scheme selection, processing method, calculation and analysis of the foundation were discussed.Keywords:composite foundation; ultimate bearing capacity; settlement; pile foundation作者簡(jiǎn)介：丁杭普，高級(jí)工程師，一級(jí)注冊(cè)結(jié)構(gòu)工程師，Email：arnoldman@163.com。參考文獻(xiàn)［1］GB 50007—2011 建筑地基基礎(chǔ)設(shè)計(jì)規(guī)范［S］.北京：中國建筑工業(yè)出版社，2012.［2］顧曉魯，錢鴻縉，劉惠珊，等.地基與基礎(chǔ)［M］.3版. 北京：中國建筑工業(yè)出版社，2003.［3］閆明禮，張東剛.CFG樁復(fù)合地基技術(shù)及工程實(shí)踐［M］.2版.北京：中國水利水電出版社，2006.［4］陶景暉，梁書亭，金如元，等.復(fù)雜地質(zhì)條件下高層建筑剛性樁復(fù)合地基應(yīng)用與研究［J］.建筑結(jié)構(gòu)，2013，43(6):86-91.
