摘要
北京奥林匹克篮球馆屋盖结构跨度大,单榀桁架最重达163t,桁架最高达9.6m,施工难度大。经对高空滑移、高空拼装和整体提升三种方案进行比较,认为分段滑移方案能保证工期和质量安全要求,又对三种高空滑移方案在挠度、应力和支点反力等方面的优劣进行对比,最终决定采用三滑道滑移方案。
The stadium roof structure is big-spanned, and with maximum single truss weight of 163t and maximum truss height of 9.6m, it is difficult to construct. By comparing the alternatives of high-altitude sliding, high-altitude assembly and integral lifting, it was believed that plan of segmental sliding could ensure schedule, quality and safety of the project. After the three alternatives of high altitude sliding being evaluated in respects of deflection, stress and support force, the sliding plan with three slide tacks was finally selected.
