摘要
云南龙江特大桥为西部强震山区的1座大跨度悬索桥,其加劲梁采用钢箱梁,受山区运输条件所限,钢箱梁总拼需在现场索塔附近制造。论文探讨钢箱梁制造过程中板单元制作、钢箱梁现场总拼与涂装、运输与存放一系列布局设计,做到布局合理,安全可靠,经济适用,强有力地保障了龙江桥项目建设。
For strong earthquake in western mountainous area of yunnan province longjiang super major bridge a long-span suspension bridge.Stiffening girder with steel box girder, the mountainous area and the limit of the transport conditions, steel box girder must spell the site should be located in the bridge on both sides of the main tower, this paper discusses steel box girder manufacturing process unit of Plate unit production, steel box girder general assembly and coating, a series of layout design,transport storage do layout is reasonable, safe and reliable, affordable, powerful guarantee of the longjiang bridge projects.
