［摘要］目前我国开合屋盖系统的发展还处于初始阶段，这方面的设计经验和技术成果较少。结合中国轻纺城体育中心体育场开合屋盖设计中的一些经验及设计关键环节进行介绍。根据该工程固定屋盖跨度大、建筑高度低、结构刚度要求大的特点，介绍了所采用的新型并联式柔性下弦组合桁架结构设计。同时根据浙江地区淤泥质土桩基水平承载力较低的特点，对释放自重产生的水平力进行了简要分析。最后，对开合结构屋盖设计提出几个方面的总结和建议。

Abstract:The current development of retractable roof system in China is still in the initial stage, and there are few design experience and technical achievements in this area. The experience and design key processes of retractable roof of China Textile City Sports Center Stadium were introduced. The project has characteristics of large-span fixed roof, low construction height and large structural stiffness requirement. The new type of parallel flexible composite bottom chord truss structure was introduced. According to the characteristics of low horizontal bearing capacity of the pile foundation of the silt soil in Zhejiang provincial area,  the horizontal forces generated by releasing the self-weight was briefly analyzed. Finally, several  summaries and suggestions for retractable roof structural design were put forward.

Keywords:stadium; retractable roof; movable roof; fixed roof; drive and control system; parallel flexible composite bottom chord truss
