摘　　要：马鞍形体育场大悬挑钢结构施工成形阶段的变形以及构件应力对环境温度变化极为敏感。结合商丘市体育场罩棚钢结构工程,对其在施工过程的温度效应进行了相关研究,具体包括了合龙施工缝的设置、结构安装温度的影响、合龙温度的确定等,在此基础上,给出一些关于合龙施工的建议,希望能为类似马鞍形体育场大悬挑钢结构的施工提供一些参考。The deformation and stress of the large cantilevered steel structure of the saddle-shaped stadium in the construction forming stage are extremely sensitive to the change of environmental temperature.Combined with the steel structure project of Shangqiu stadium canopy,the temperature effect in the construction process is studied,including the setting of closure construction joints,the influence of structural installation temperature,and the determination of closure temperature.On this basis,several suggestions about closure construction are given,so as to provide reference for the construction of large cantilever steel structure of similar saddle-shaped stadium.
