摘要
上海长江大桥位于长江入海口,跨越长江北港,全长16.55 km,其中跨江段桥梁是一座巨型组合桥,长9.97 km,由主航道桥、辅航道桥与非通航孔桥组成。主航道桥需通行5万吨级船舶,桥型采用主跨730 m的双塔双索面分离式钢箱梁斜拉桥,人字形桥塔,设计中预留了轨道交通线空间。着重介绍主航道桥的设计。
Shanghai Changjiang River Bridge is located at the estuary of the Changjiang River and spans the north channel of the river . The total length of the Bridge is 16. 55 kin, of which the part of the Bridge crossing the river is a huge composite girder bridge that accounts for a length of approximately 9.97 km and is composed of the main shipping channel bridge, auxiliary shipping channel bridges and non-navigable span bridges. For the main shipping channel bridge, it is required that a navigational clearance for 50 000 DWT ships should be provided underneath the bridge and the structural type selected for the bridge is hence a separated steel box girder cable-stayed bridge having a main span of 730 m, double pylons in inverted Y-shape and double cable planes, and the space for arrangement of the light rail transit lines is preserved on the bridge in design. In this paper, the design of the main shipping channel bridge is highlighted.
