浙江千岛湖南浦大桥钢管拱肋吊装方案

Installation Design for Steel Tube Arch Rib of Nanpu Bridge over Qiandao Lake in Zhejiang Province

无支架缆索吊装及钢铰线斜拉扣挂施工方法对于大跨度拱桥的修建具有较大的推动作用,它有较强的适应性,尤其在陡峭山谷地带其作用更为明显,而桩式地锚的成功运用更进一步降低了这种施工方法的成本,在陡峭山谷施工极其方便,既可保护生态又方便其施工材料的运输,也可为复杂山区修建大跨度拱桥提供借鉴。

Non-support cable crane and stranded wire cable stayed construction can promote the reconstruction of long-span bridge. It has strong adaptability, especially at the abrupt valley. Meanwhile,successful application of anchor pile further reduces the cost of this construction, and it is most convenient for the construction in the abrupt valley, which not only protects ecological environment and facilitates the transportation of construction material, but also serves as guidance for constructing long-span arch bridge at complex mountainous region.
