The super structure type of ground is frame-shear wall structure. There are relative weak underlying layer of 6 meters below the basement. There are large load in the frame-core walls structure while the underground garage is in over-compensated state. The control of differential settlement is difficult. Different combinations of foundation types and ground types have been compared, in which foundation types include beam and slab raft foundation and plate foundation, and ground types include artificial foundation (bored pile and CFG pile composite foundation) and natural foundation. By adjusting the stiffness of the basis and the structure, CFG pile composite foundation and natural foundation are used. Through the results of calculation and measurement of settlement deformation, the foundation design scheme is reasonable, economical and feasible, and meeting the codes requirements.Keywords: large chassis building; differential settlement; geotechnics; design; calculation; foundation作者簡介：方云飛，碩士，工程師，全國注冊土木工程師（巖土），Email：fangyunfei@126.com。參考文獻［1］王曙光, 滕延京. 大底盤建筑主裙樓基礎整體連接的可行性與適用性研究［J］. 土木工程學報, 2012, 43(2):95-99.［2］GB 50007—2011 建筑地基基礎設計規(guī)范 ［S］. 北京: 中國建筑工業(yè)出版社,2011.［3］王旭, 陳林, 楊潔, 等. 銀河搜候(SOHO)中心結(jié)構設計［J］. 建筑結(jié)構,2011,41(9):63-68.［4］DBJ 11-201—2009 北京地區(qū)建筑地基基礎勘察設計規(guī)范［S］. 北京: 中國計劃出版社,2009.［5］中國建筑標準設計研究院. 全國民用建筑工程設計技術措施: 結(jié)構. 地基與基礎［M］. 北京: 中國計劃出版社, 2009.
