（1 北京五豪世紀建筑設計有限公司,100036；2 中國紡織化纖工程總公司 北京 100037；3中國建筑科學研究院，100013）［提要］國美家園工程主樓采用CFG樁復合地基，與主樓相鄰的地下車庫采用獨立基礎加防水板的結構形式，對主樓承載力做了適當?shù)纳疃刃拚瑱z測結果表明，該工程是安全的，且技術、經(jīng)濟效益顯著。建議裙房或車庫基礎為獨立柱基加防水板時，對主體結構地基承載力的深度修正問題應作進一步深入研究。［關鍵詞］CFG樁復合地基；獨立基；深度修正Application of CFG Pile Composite Foundation in Engineering of Gome Homestead/Guan Weilan1, Li Chunfang2, Tong Jianxin3, Yan Mingli3 (1Beijing Wuhao Century Architecture Design Co., Ltd., Beijing 100036,China;2China Texile and Chemical Fiber Engineering Corporation,Beijing 100037,China;3China Academy of Building Research, Beijing 100013,China)Abstract:CFG pile composite foundation is applied in the main building of Gome Homestead. Isolated foundation joined with waterproof board is adopted in underground garage beside the main building. Depth correction is considered in calculating the bearing capacity of main building. The results show that the project is safe and the technical and economic benefits are notable. When the foundation of podium or underground garage adopts isolated foundation joined with waterproof board, it advises that the problem of shaping of depth to bearing capacity of main building should be studied more.Keywords:CFG pile composite foundation； isolated foundation； shaping of depth
