摘　　要：武汉体育中心二期主体育馆屋盖为双层扁平张弦网壳。结合该结构的施工特点,运用大型集群控制液压千斤顶进行中心区域整体顶升、空中悬停接长,四周区域采取满堂红脚手架高空散装的施工方案。并借助ANSYS有限元分析软件,根据施工顶升步骤,进行有限元建模分析,模拟施工工况,为方案的实施提供充分的理论依据。实践证明根据数值模拟分析结果进行针对性的预案措施准备是确保施工顺利实现的保障。Main Stadium roof of Wuhan Sports Center Second phase is the flat double-reticulated shell-string structure. Based on construction characteristics of the structure, central area structure was integrally hoisted by large-scale thinking controlled hydraulic jack, and then was jointed in length at high space. Correspondingly, peripheral areas were supported by over-site scaffold, and were jointed at high altitude. Based on hoisting steps, construction conditions were simulated by ANSYS software to provide theoretical basis for construction scheme. Practice shows that smooth construction can be ensured by pertinence scheme preparation according to simulating results.
