摘　　要：卢赛尔体育场为超大跨度双轴对称马鞍形空间张拉索膜结构,具有结构体量大、设计要求严格、安装精度要求高等特点。本文介绍了体育场主体钢结构的结构体系、构件形式及规格、球铰支座设计特点、临时支撑架的布置和主要的施工顺序。通过施工过程分析,计算得到了V柱预变形数值以及施工过程中结构的变形和受力情况,为现场施工提供了技术指导和理论支持,同时可为今后其他类似工程提供参考。Lusail stadium is a super-long-span and biaxially-symmetric saddle-shaped space tension cablemembrane structure.It is a heavy and large structure with strict design requirements and high accuracy of installation requirements.In this paper its main steel structure was introduced including structure system,component forms and specifications,spherical bearing,layout of temporary towers and main construction sequence.By construction process analysis,pre-deformation value of V frame and the deformation and stress of main steel structure were obtained,which provided technical guidance and theoretical support for on-site construction.And it can provide references for other similar projects in the future.
