摘　　要：上海世博演艺中心基地北侧为黄浦江并紧邻黄浦江驳岸,南侧为临近运营当中的地铁M8线区间隧道,环境保护要求较高,而且作为中国2010年上海世博会的主要场馆,工程工期有着极高的要求。文章介绍了该基坑工程的工程概况及总体设计方案,重点说明其中微承压水的处理技术措施、临水基坑工程的设计、超大直径圆环支撑以及创新性采用周边基础环板作为换撑的关键技术,并对主要的监测结果作了分析。该基坑工程已顺利完成,设计方案的实施为主体地下结构的施工和实现预定的工期目标创造了有利的条件,有效地保护了基坑周边的环境。The Shanghai Expo Performance Center（ SEPC ）, which has very strict construction time limit, is one of the main venues of World Expo 2010 Shanghai. It is situated near the Huangpu River. The NO. 8 Metro is adjacent to the south side of the excavation of the SEPC. The metro has a very strict deformation control requirement. This paper firstly introduce an overview of the SEPC foundation Project and the overall design scheme of the deep excavation. Then, emphases are put on some of the key techniques, including treatment of micro confined groundwater, design of the north side which is close to the Huangpu River, design of super large circular structs, and design of the peripheral part of the bottom slab which is used as struct. Finally, the monitored data are analyzed. The accomphshmeut of the design scheme of the deep excavation has effectively protected the environment of the excavation and provided conven- ience to the construction of the main structure of the SEPC Project.
