摘　　要：宝安体育场屋盖结构为车辐式张拉结构,采用定尺定长设计与张拉技术施工方法,为了解屋盖结构在不同施工张拉阶段的实际位移,分别在上牵引索索长为8.00,1.00,0.60,0.30,0.00(m),下牵引索索长为5.00,1.00,0.60,0.20,0.00(m)的工况下,模拟计算外压环和上、下径向索节点的空间位置,并在张拉过程中对应计算工况进行现场监测,得到屋盖结构在张拉阶段的位移参数,将实测值与模拟计算值进行对比,两者吻合良好,验证了该理论计算和现场实测都是正确和可行的。The roof of Baoan stadium is a typical spoke structure, the cables of the structure are used fixed length during designing and tensioning. Obtain the real displacement of the roof structure in different stages is important for engineering construction, thus, use finite element analysis soft respectively calculate the spatial position of nodes on outer ring beam, upper and lower radial cable when the upper radial cables length are 8.00, 1.00, 0.60, 0.30, 0.00（m） and when the lower radial cables length are 5.00, 1.00, 0.60, 0.20, 0.00（m）. In tension stage, site monitoring is carried out according to the calculation progresses, and obtained the deformation parameters of roof structure in different tensioning stages, through comparing the actual monitoring value with theoretical calculation value find that both of them coincide well, the comparing result proved that both of actual monitoring value and the theoretical calculation value are correct and feasible.
