摘　　要：体育场挑棚为空间管桁架结构,呈圆弧形,施工时采用钢管临时支撑系统,整个体育场的挑棚结构在施工阶段的受力情况与最终结构的受力情况不同。在结构分析计算的基础上,按照等比例下降的原则进行结构的卸载,同时对钢结构变形进行检测,保证施工安全和工程质量。Some stadium canopy adopts temporary pipe support system.The structure stress of whole stadium canopy is different in construction stage and finally stage.Based on analysis and calculation,structure was unloaded according to principle of proportional decreasing.At the same time,deformation of the steel structure was monitored in order to assure construction safety and engineering quality.

关 键 词：挑棚 桁架结构 临时支撑 卸载
