摘　　要：徐州市奥体中心体育场工程屋盖雨篷采用了一种新的结构形式——环向悬臂索承网格结构。对徐州市奥体中心体育场屋盖预应力施工的关键技术进行了研究,主要内容包括预应力施工仿真分析、预应力拉索的安装、预应力施加方法等。通过本文的研究分析将形成一套环向悬臂索承网格结构体系的施工关键技术,该结构体系适用于超大型的体育场及其他公共建筑。Combining with the project of Xuzhou Olympic Sports Center Stadium, the roof awning of the project adopts a kind of new structure form of the ring cantilever cable supported latticed structure. In this paper, the key technology of prestressed construction of Xuzhou Olympic Sports Center Stadium roof is studied, and the main content includes the analysis of prestressed construction simulation, prestressed cable installation, prestressing method etc.. Through the research and analysis, it will form a set of structure system and construction key technology. This structure is suitable for super large stadium and other public buildings.
