沿江高速铁路建设实施方案研究

随着长江沿线城市化进程的加快和经济社会的发展,既有沪汉蓉铁路已经逐步不适应国家战略要求和沿线城市群间快速通达需求。高速铁路具有运量大、成本低、能耗小、占地少等优势,是绿色、大众化的交通工具。结合国家中长期高速铁路网规划,通过阐述沿江铁路通道发展现状及存在问题,结合通道内各区段预测客流量提出规划方案;最终形成沿江高速铁路"三步走"建设实施方案,有利于完善长江立体综合交通走廊建设,缩短时空距离,优化综合运输结构体系。

A Study on the Implementation Plan of the Yangtze River High-Speed Railway

With the urbanization and the development of society and economy along Yangtze River, existing Shanghai-Chengdu Railway cannot adapt to the national strategy and the fast access of city clusters along the line. High-speed railway is a environmental and popular transport mode which is well-known for its high capacity, low cost, less energy consumption and less land use. Based on the national medium and long-term high-speed railway network planning, this paper elaborates the current situation and challenges of Yangtze River railway corridor and proposes a planning based on the traffic forecast of each section. Finally, a three-step construction implementation plan for the high-speed railway along Yangtze River is proposed. It is helpful to improve the construction of the integration transportation corridor of Yangtze River, shorten the space-time distance, and optimize the comprehensive transportation structure system.
