摘　　要：凤凰山体育中心项目工程创造性地采用了“葵花形”钢网架+大开口索穹顶结构,其结构受力表现形式特殊,支撑体系结构新颖,与屋盖交叉施工作业多,施工难度大。其中外立面斜向摇摆柱的临时支撑结构、看台柱焊接安装方法以及数值模拟协同施工等关键技术的运用,既有效确保安装质量,又保证了施工过程安全。该支撑体系施工技术的成功运用,为今后类似柔性屋盖支撑体系的施工积累了成熟的经验。The Phoenix Mountain Sports Center Project innovatively adopts the"sunflower shaped"steel grid+large opening cable dome structure,which has special stress expression form,novel support system structure,many crossed construction operations with the roof,and great construction difficulty.The application of key technologies such as the temporary support structure of the inclined swing column of the facade,the welding and installation method of the viewing platform column and the collaborative construction of numerical simulation not only effectively ensures the installation quality,but also ensures the safety of the construction process.The successful application of the support system construction technology has accumulated mature experience for the construction of similar flexible roof support system in the future.
