摘　　要：结合工程实例,针对螺栓球节点高空散拼施工难度大、安装精度难以控制等问题,重点介绍了大跨度螺栓球节点网架高空散拼施工过程中网架结构和临时结构的安全性分析。同时对临时支撑横杆、立杆等进行稳定性验算,均符合规范要求。According to engineering practice, for the difficulties of high altitude assembling construction and installation precision, the safety analysis for space truss structure and temporary supports of high altitude assembling construction for large-span space truss with bolt ball was introduced in detail. Meanwhile, the stability checking for cross bar and pole of temporary supports was done, whose results could meet code requirements.
