宝中铁路增建第二线引入平凉地区方案研究

A Study Plan on Rebuilding Baozhong Railway Addition Second Line to Pingliang Area

目前宝中铁路运输能力紧张,难以满足日常运输需求,已成为区域路网中的瓶颈。为从根本上解决这种状况,必须尽快增建第二线,形成双线、快速的大能力通道。研究结合区段运输特点,选择合适的技术标准,对废弃既有线不限速和利用既有线限速两套方案进行比较,选择了经济合理的改建方案。增建二线完成后,宝中铁路将对构筑区际大能力通道,积极推进丝绸之路经济带铁路运输骨干通道建设提供支撑和促进作用。

The current capacity of Baozhong railway is limited,it is difficult to meet the daily transportation demand,and has become a bottleneck in the regional railway network.In order to fundamentally solve this situation,it is necessary to build a second line as soon as possible to form a double-line,fast and high-capacity channel.Combining with the characteristics of section transportation and appropriate technical standard,two sets of reconstruction schemes of abandoning the existing line without speed limit and using the existing line with speed limit are compared,and the economical and reasonable reconstruction scheme is selected.After the completion of the construction of the second line,the Baozhong railway will provide support and promotion for the construction of interregional large capacity channel and actively promote the construction of the backbone railway transportation channel of the Silk Road Economic Belt.
