［摘要］針對巖溶地區(qū)某高層住宅基礎的選型與設計，詳細論述了CM樁復合地基的工程特性、計算方法和檢測評價。結果表明復合地基的承載力提高顯著，沉降計算結果與實測值接近，證明該工程采用CM樁復合地基較好地滿足了建筑安全和使用要求，具有造價低、工期短的優(yōu)點。［關鍵詞］CM樁復合地基；剛性樁；巖溶；沉降中圖分類號：TU472文獻標識碼：A文章編號：1002-848X(2012)06-0118-03Application of CM three-dimension composite foundation in high-rise building in the karst districtWan Zhiyong, Han Jianqiang, Gao Yubin, Wang Wei（Guangzhou Design Institute, Guangzhou 510620, China）Abstract: The selection and design of the foundation in high-rise building in the karst district were discussed, which focused on the engineering characteristics, calculation method, detection and evaluation of CM three-dimension composite foundation. The results show that the bearing capacity of the composite foundation has been improved successfully, and the calculated settlement is approximate to the measured one. CM three-dimension composite foundation adopted in this project can satisfy the building safety and application requirement, and short time limit and less expense are its features.Keywords: CM three-dimension composite foundation; rigid pile; karst; settlement作者簡介：萬志勇，高級工程師，一級注冊結構工程師，Email:wanzhiyong@gzdi.com。參考文獻［1］GB 50007—2002建筑地基基礎設計規(guī)范［S］.北京：中國建筑工業(yè)出版社，2002.［2］JGJ/T 210—2010剛-柔性樁復合地基技術規(guī)程［S］.北京：中國建筑工業(yè)出版社，2010.［3］沙祥林.CM三維高強復合地基［C］//第十屆土力學及巖土工程學術會議論文集，2007.［4］JGJ 79—2002建筑地基處理技術規(guī)范［S］.北京：中國建筑工業(yè)出版社，2002.
