摘　　要：杭州奥体中心主体育场工程顶环梁结构复杂,支模条件恶劣,传统的支承架体难以达到功能合理、费用优化、进度保证的目标。提出并设计出一种新型塔吊标准节支承高空支模钢平台体系。通过方案对比、理论分析、有限元模拟等一系列研究计算,对该支撑体系的搭设工艺、设计方法、结构性能及构造进行充分论证,并将其运用到实际工程,圆满完成顶环梁的施工,提出几点施工要点措施,供今后类似工程借鉴应用。The roof ring-beam of the main stadium of Hangzhou Olympic Sports Center has complex construction and poor support condition. The traditional support frames are difficult to achieve the goal of reasonable function, cost optimization and schedule guarantee. A steel platform system of high-altitude bearing supported by the standard section of tower crane is proposed and designed. By comparison and analysis, theoretical analysis, finite element simulation and a series of research and calculation, the erection process of the supporting system technology, design methods, structural performance and construction are fully argued. Then the bearing system is applied to the actual project and the roof ring-beam construction is successfully completed. Finally, put forward some points of construction which can be used in future similar projects.
