（北京市建筑设计研究院有限公司，北京100045）[摘要] 援赞比亚体育场结构布置较为复杂，下部看台由68榀钢筋混凝土框架环绕体育场场心组成，各榀框架高度不同，随屋顶罩棚的曲线外形由高到低。屋顶罩棚网架由落地的倾斜巨型格构拱架（主拱，跨度288m）及一端与主拱汇交、其他支撑点落于混凝土柱顶的格构拱架（次拱），主次拱间设有空间网架，而形成稳定的空间结构体系。本文主要介绍了主拱的箱墩式基础和主体框架基础设计，主体混凝土结构和屋顶罩棚的结构选型和分析。[关键词] 体育场；复杂结构；墩基础；落地大拱；网架中图分类号：TU393.3,TU318 文献标识码：A 文章编号：1002-848X(2013)S2-0313-06作者简介：王荣芳，工学硕士，工程师，一级注册结构工程师，Email：wangrfang@126.com。Structural design of Zambia Sports StadiumWang Rongfang, Long Yibing, Liang Congzhong, Zhu Zhongyi, Qin Kai, Sun Hongwei（Beijing Institute of Architectural Design, Beijing 100045, China）Abstract：The structural arrangement of Zambia Sports Stadium is complex. The stadium's stand is made up of 68 pieces of reinforced concrete frames circling the stadium center. The height of every frame is different, which is from high to low with the curves of roof of the stadium. The main structures under stress are the huge floor-inclined lattice arch centering (main arch，span 288m) and the lattice arch centering (subordinate arch), which joins with the main arch at one end, other bracing points of which are on the top of concrete column; space grid is provided between the main and subordinate arches, which forms stable space structural system. This paper introduced the pier foundation like a box of the main arch and the foundation of the main structure, the structure selections of the main reinforced concrete frames and the steel roof.Keywords： stadium; complex structure; pier foundation; the huge floor-inclined arch; grid structure
