吴淞江工程（罗蕰河北段）跨河桥梁方案研究

Conceptual Design of Cross-River Bridges for the Wusong River Project (Northern Section of the Luowen River)

摘要:

吴淞江工程是国务院批复的《太湖流域防洪规划》确定的重大工程之一，包括河道疏浚与新开、新建水利枢纽设施、沿线跨河桥梁新建及改建等建设内容，采用分段实施，罗蕰河北段为吴淞江工程的有机组成部分，河道总长5.88 km，需建设桥梁7座（4座车行桥，3座人非桥），首先开展了各类桥型的适应性论证与比选分析，同时以该工程为例，从总体设计思路到单体桥梁方案，阐述了桥梁群方案选型思路与方法，为城市跨河桥梁群的方案设计提供参考。

Abstract:

The Wusong River Project is one of the major projects specified in the Taihu Lake Basin Flood Control Plan approved by the State Council.It covers construction works including river channel dredging and new excavation, construction of water control hub facilities, as well as the new construction and reconstruction of cross-river bridges along the line, and adopts a phased implementation approach. The Luowen River section serves as an integral component of the Wusong River Project, with a total river course length of 5.88 km and 7 bridges to be constructed (4 vehicle bridges and 3 pedestrian and non-motorized vehicle bridges). The adaptability demonstration and comparative selection analysis of various bridge types is first conducted. Meanwhile, taking this project as a case study, it elaborates on the ideas and methods for the scheme selection of bridge groups, ranging from the overall design concept to individual bridge schemes, thus providing a reference for the scheme design of urban cross-river bridge groups.
