上海长江大桥跨江段桥梁设计

Design of Spanning-river Bridge of Shanghai Changjiang River Bridge

上海长江大桥全长16.5km,是目前我国最大的公路与轨道交通合建的跨江桥梁。设计中根据大桥的建设条件与特点.开发与应用了公轨合建、大跨度斜拉桥、大跨度组合梁、大型预制构件、节段拼装主梁等新技术、新结构、新工艺.为大桥的建设提供了技术支撑。该文着重介绍了上海长江大桥跨江段桥梁的设计与科研。

The total length of Shanghai Changjiang River Bridge is 16.5 kin.It is the largest span- ning-fiver bridge constructed together with the highway and the rail traffic in China.Based on the construction conditions and the characteristics of the bridge,the new technique,the new structure and the new technology of the highway and rail tragic constructed together,the large-span ca- ble-stayed bridge,the large-span built-up beam,the large-sized prefabricated member and the main beam assembled by segments are developed and applied in the design in order to provide the tech- nical support for the construction of the bridge.The article focuses the introduction on the design and the scientific research of the spanning-river bridge of Shanghai Changjiang River Bridge.
