摘　　要：深圳宝安体育场屋盖为轮辐式索-桁结构+膜结构组合形式。屋盖索-桁结构是膜结构的支撑骨架,由上内环索、下内环索、飞柱、外环梁及36片三角形径向索网组成,施工的关键是径向索的整体张拉。钢索数量多、荷载大、工期紧,施工难度非常大。在对各种张拉方案进行仿真模拟计算后,最终确定了先提升上径向索就位,再提升张拉下径向索就位,最后安装悬挂索的张拉方案,并采用计算机自动控制整体张拉系统进行张拉施工。The roof of Shenzhen Bao＇an Stadium is a composite structure which is composed of cable-truss structure and membrane structure.The cable-truss structure is the support skeleton of membrane structure.The roof is consists of upper ring cables,lower ring cables,flying columns,outer compression ring beam and 36 cable trusses.The key process is integral lifting of radial cables.Under conditions of large steel cables quantities,heavy loading and short construction period,it is very difficult to construct.After all kinds of methods are compared and simulated,the construction methods of lifting upper ring cables firstly,then lifting lower ring cables and installing suspended cables are decided.The synchronized automatic control system is used to tension the cables.
