某大型体育场馆开合屋盖变形监测及分析

Deformation monitoring and analysis of a large sports venue retractable roof

结合某体育馆采用的大型开合屋盖的设计施工实例,介绍了轨道开合屋盖结构的荷载组合情况,为了确保开合屋盖工程的稳定性和安全性,对在施工和使用阶段的主桁架、环桁架以及活动屋盖的变形量进行了监测和分析,发现变形量均在正常范围内,满足体育场工程的设计规范要求。

Combined with the design and construction of a stadium with retractable roof, detail the load combination track retractable roof struc-ture. In order to ensure the stability and safety of the retractable roof engineering, deformation on the main truss, in construction and use phase of the ring truss and roof were monitored and analyzed. The deformation were found in the normal range, meet the design specification require-ments of the stadium project.
