摘要
上海长江大桥位于长江入海口,越江桥梁长9.97 km,桥梁预留轨道交通过桥功能。为适应复杂建设条件采用分离式钢箱梁斜拉桥、大跨组合箱梁以及多种跨度的PC箱梁等多种结构形式,采用对称悬臂拼装、整孔预制吊装、节段预制拼装等多种施工方法。重点从大跨度斜拉桥、大跨度组合箱梁、桥梁预制拼装以及公轨合建等方面介绍上海长江大桥的设计与构思。
Shanghai Changjiang River Bridge is located at the estuary of the Changjiang River. The part of the Bridge crossing the river is approximately 9.97 km long and the function of the light rail transit is preserved on the Bridge. To accommodate the complicated construction conditions of the Bridge, several types of the structures, such as the separated steel box girder cable-stayed bridge, the long span steel and concrete composite box girder and the prestressed concrete box girder of different span length are adopted, and the various construction methods of the balanced cantilever assembling, the full span girder prefabrication, lifting and installation and the segmental precasting and assembling are respectively applied. In this paper, the overall design and design consideration of the Bridge are highlighted mainly from aspect of the long span cablestayed bridge, the long span composite box girder, the precasting and assembling and the combined construction of the highway and light rail transit.
