［摘要］廣州太古匯地下室長283.5m、寬154.35m、深21.5~22.5m。超大超深基坑采用了多種支護形式；地下超長混凝土結(jié)構(gòu)采用后澆帶，并在混凝土中摻加聚丙烯短纖維，以控制混凝土的收縮裂縫；抗浮采用抗拔樁，部分用抗拔錨桿；防水設(shè)計采用“剛?cè)嵯酀⒎琅沤Y(jié)合”的方式，以達到建設(shè)方要求地下室干爽的要求。［關(guān)鍵詞］超大超深基坑；支護形式；抗拔樁；抗拔錨桿；剛?cè)嵯酀环琅沤Y(jié)合中圖分類號：TU473.2，TU753.6文獻標識碼：A文章編號：1002-848X(2012)06-0103-04Design and construction for extra-long and extra-deep basement and its foundation of Guangzhou Taikoo Hui projectGao Lin, Wang Yundan, Zhou Ding, Fu Zhiliang, Wang Wenjie(Guangzhou Design Institute, Guangzhou 510620, China)Abstract: The basement of Guangzhou Taikoo Hui project is 283.5 meters long, 154.35 meters wide and 21.5 to 22.5 meters deep. Many supporting forms are adopted in the extra-big and extra-deep foundation pit. The post-cast strip and concrete with durafiber are used in the extra-long concrete structure design to control concrete shrinkage crack. Uplift piles and uplift boltings are used in anti-floating design. The method of perfect combination of hardness with softness and waterproof with drainage is used in water-proof design in order to achieve the aim of keeping the basement dry and comfortable.Keywords: extra-big and extra-deep foundation pit； supporting form； uplift pile； uplift bolting； hardness with softness and waterproof with drainage作者簡介：高琳，高級工程師, Email：gaolingz@126.com.參考文獻［1］廣州報業(yè)廣場巖土工程勘查報告［R］.廣州:廣州市城市規(guī)劃勘測設(shè)計研究院,2001.［2］太古匯廣州報業(yè)廣場基坑工程巖土工程勘查報告［R］.廣州:廣州市設(shè)計院,2004.［3］史佩棟，高大釗，桂業(yè)琨.高層建筑基礎(chǔ)工程手冊［M］.北京:中國建筑工業(yè)出版社,2000.［4］DBJ 1531—2003建筑地基基礎(chǔ)設(shè)計規(guī)范 ［S］.北京:中國建筑工業(yè)出版社,2003.［5］GB 50108—2008地下工程防水技術(shù)規(guī)范 ［S］. 北京:中國計劃出版社,2009.
