四川对外铁路快速通道建设时序研究

Research on the Time Sequence of External Railway Rapid Passage Construction in Sichuan

研究目的:在既有铁路、在建铁路、拟建铁路的基础上,分析四川省各个方向铁路输送能力与需求的适应情况,并根据运能与需求的适应情况确定四川对外铁路通道的建设时序。研究结论:四川省的铁路建设应集中力量先建对外通道,缓建内部通道。在拟建铁路中,立即开工建设兰渝铁路和遂渝铁路复线;在规划铁路中,建设顺序依次为成昆铁路提速扩能、西安至成都客运专线、成都至拉萨铁路、成都至贵阳铁路,上述4条铁路均应在2018年以前建成通车。

Research purposes： On basis of existing railway, under - construction railway and proposed railway, this paper analyses the suitability of Sichuan railway transportation capacity and demand to determine the time sequence of external railway rapid passage construction in Sichuan. Research conclusions：In Sichuan railway construction, we should concentrate onto building the external passage first and later building the internal passage. In proposed railway construction, the double line on the Lanzhou - Chongqing railway and Suining - Chongqing railway will be built immediately. In the plan of railway, the sequence of railway construction is in turn the Chengdu - Kunming railway for raising the speed and transportation capacity, Xi＇an - Chengdu passenger dedicated line, Chengdu - Lasha railway, Chengdu - Guiyang railway. The four railways mentioned above will be completed and operated in 2018.
