摘　　要：长江/洞庭湖模型试验大厅采用了提篮拱、吊杆和拉索网架组合成的新颖空间结构,其网架拉索和拱吊杆的张拉施工复杂。作者以设计思路为基础,通过ANSYS有限元程序计算,分析了张拉互相影响,确定了张拉顺序、次数和张拉力,为施工提供了一个科学准确的理论依据和指导。A novel space structure ＂Basket handle arch-Suspender-Prestressed grid＂ is adopted to Yangtze River-Dongting Lake Model Test Hall. The tension construction of the truss-cables and the arch-suspenders is very complicated. Based on the ideas of design, the tension affection of the cables and the structure was analyzed by ANSYS finite element simulation calculation, then the tension sequence, times and forces were put forward, which offered scientific and accurate foundation and guidance for the tension construction.
