摘　　要：广晟国际大厦屋顶设置了阶梯式单管塔天线,根据结构特点和施工合理性要求,天线采用先套筒后分步整体提升法安装。针对超高空提升安装作业、精度要求高等施工特点,介绍了天线安装施工过程中的难点及关键技术,并对提升安装施工全过程进行了有限元仿真分析。结果表明:该安装方法合理可行,能够满足结构安全性要求;对此类特种结构的安装施工进行施工全过程的预分析,可有效评估和调整施工方案,以确保实际结构施工的合理安全。The single-tube antenna tower is designed on the top of Guang-sheng International Building. Based on the structural characteristics and construction reasonable requirements, the method of integral canular lifting is applied to install the antenna. In allusion to the ultra-high-altitude installation with high precision construction, the construction difficulties and key technologies of the antenna installation is introduced. The whole construction process was analyzed by finite element simulation. The results show that： The installation method is reasonably practicable and it can meet the structural safety requirements. Pre-analysis of whole construction process for such special structure can effectively evaluate and adjust the construction scheme, and ensure the actual structural construction reasonable and safe.
