黄浦江首座公轨双层桥——闵浦二桥引桥工程总体方案研究

General Design Scheme Study of Approach Bridge of Second Minpu Bridge (First Road and Rail Double Deck Bridge Crossing Huangpu River)

上海市轨道交通5号线南延伸工程跨越黄浦江节点与沪闵路-沪杭公路地方交通越江工程结合(即闵浦二桥新建工程),采用上下双层一体化结构形式。结合一体化区间引桥段桥梁型式,对各种方案的结构合理性、交通功能、对景观与环境的影响、工程量以及车站布置等方面进行了研究和论证,最终推荐"干"字形的独柱桥墩为实施方案。

The south extension project of Rail Transit Line 5 combines with a new local bridge project (i.e.the new Minpu Bridge) at the Huangpu River crossing section.The two crossing structures are integrated in- to one up-down double deck structure.Combined with the style of integrated bridge approach,several design schemes are studied in the aspects of structural rationality,traffic function,impact on landscape and environment,engineering cost and metro station plan.The final design is adopted as a single col- umn pier supportincl double deck.
