沿江高铁武汉至合肥段方案研究

Study on the Scheme of Wuhan-Hefei Section of High-speed Railway along the Yangtze River

结合路网构成及项目特点,首先对武汉至南京段通道总体布局及相互替代性进行分析,得出利用相关线路分流替代不可行;其次在分析运输需求、建设目标、方案构成的基础上,利用比较法、综合分析法对沿江高铁武汉至合肥段建设方案进行统筹研究,推荐新建高标准客运铁路,与既有沪蓉线形成四线规模;最后对六安至合肥段建设方案进行细化研究,推荐新建高标准客运通道,与既有沪蓉线、宁西线形成六线规模。研究结论满足运输需求,符合长江经济带和中长期铁路网发展规划,可为沿江高铁通道建设提供技术支撑。

In view of the composition of the rail network and the characteristics of the project,the overall layout and mutual substitution of the passageway from Wuhan to Nanjing are analyzed.It is concluded that it is not feasible to use relevant line shunt replacement.Based on the analysis of transportation demand,construction objective and scheme composition,the construction scheme of Wuhan-Hefei section of the high-speed railway along the Yangtze River is studied comprehensively by using comparative method and comprehensive analysis method.High standard new passenger railway is recommended to form a four-line system with the existing Shanghai-Chengdu line.Finally,the construction plan of the Lu’an-Hefei section is studied in detail,and high standard new passenger corridor is recommended to form a six-line system with the existing Shanghai-Chengdu railway and Nanjing-Xi’an railway.The research results meet the transportation demand,comply with the development plan of the Yangtze River economic belt and medium and long-term railway network,and can provide technical support for the construction of high-speed railway corridor along the Yangtze River.
