摘　　要：结合常州体育馆大跨度椭球形弦支穹顶的预应力拉索施工全过程,基于有限元软件ANSYS,介绍了预应力拉索正式施工前所需的主要分析内容,并对该结构进行了精确的理论分析计算,最终使得结合可滑动索夹的环向索张拉法在该过程能够成功实施。同时根据现场施工情况,阐述了该类大跨度椭球形弦支穹顶的施工控制要点及拉索应力和结构变形监测。监测结果显示本张拉方法切实可行,能够在结构中建立有效预应力。According to the whole prestressed cable construction process of large-span elliptic suspended-dome in Changzhou Gymnasium, authors introduced some required analysis contents before prestressed cable construction based on finite element software ANSYS. According to the accurate theoretical analysis and calculation of the structure, the tension method for ring cables with sliding cable-clip was successfully implemented. Based on the on-site construction, authors presented the construction control points for the largespan elliptic suspended-dome and the monitoring of structural deformation. Monitoring results show that this tension method is feasible, which ensure the structure establish effective prestress.
