珠江黄埔大桥北汊斜拉桥钢箱梁选用具有良好抗风性能的扁平式整体钢箱梁,具有外形美观、建筑高度小,工期短、造价省,设计、制造及架设均有成熟经验等优点。主梁采用单箱三室扁平流线形栓焊钢箱梁,斜拉索在钢箱梁上采用钢锚箱形式,主梁横隔板采用整体性好、抗扭刚度大的整体板式结构。钢箱梁的防腐设计采用多层油漆的重防腐方案。
The steel box girder of Beibei cable-stayed bridge in Huangpu Bridge of Zhujiang River has the advantages of good overall wind resistance, low building height, short construction period, low cost, mature experience in design, manufacture and erection . The main girder adopts single box three-compartment flat streamlined bolt-welded steel box girder. The inclined girder adopts the steel anchor box on the steel box girder. The main girder transverse bulkhead adopts the integral plate structure with good integrity and large torsional rigidity. Steel box girder anti-corrosion design using multi-layer paint heavy-duty solutions.
