摘　　要：清丰县文体中心体育馆项目采用弦支穹顶+周边格构支撑柱结构形式,其中弦支穹顶与格构支撑柱间采用刚接。为保证弦支穹顶结构可达到施工精度要求,经过仿真模拟计算,设计预应力张拉方案、临时支撑系统、格构柱下部支撑临时限位措施、应力监测方案等,准确控制结构变形和内力,使整体结构顺利安装就位。Qingfeng County Sports Center Gymnasium project adopts the structure of suspendome +surrounding lattice support column,in which the suspendome and lattice support column are rigidly connected. In order to ensure that the suspendome structure can meet the construction accuracy requirements,after simulation calculation,the prestressed tension scheme,temporary support system,temporary limit measures for the lower support of lattice column,stress monitoring scheme are designed,the deformation and internal force of the structure are accuratly controlled to ensure the smooth installation of the whole structure.
