摘要

【目的】

宝成铁路作为连接西南西北的重要铁路通道之一，宝鸡至阳平关段现状仍为单线铁路，能力利用率93.3%，能力已饱和；同时宝阳段到发线有效长度650～700 m，牵引质量仅2600/3000 t，与前后方通道不匹配，货物列车需在秦岭、阳平关、广元等站办理摘补机车、增减轴作业，运输组织不畅。随着研究年度西北—西南、华北—西南等跨区域货物交流日益旺盛，对宝成通道的扩能改造需求凸显。

【方法】

研究基于宝成铁路存在的问题、功能定位及运输需求，以构建满足运输能力需求、安全可靠的大能力高标准通道为目标，结合不同段落线路特征，采用“分层次、分段落”的研究方法，提出单线扩能、增建二线和新建双线三大建设方案。方案充分考虑地质灾害影响、合理利用既有线，从工程投资、运输组织、运输能力等层面对建设方案进行综合比选。

【结果】

分析表明，宝鸡至秦岭段采用新建双线、秦岭至阳平关段采用增建二线并延长到发线有效长度至850 m方案与区域铁路运输通道匹配性好，满足研究年度运输需求且工程投资节省，为宝成铁路扩能改造更好发挥通道运输效益提供参考。

【结论】

方法及成果可为同类研究提供指导与借鉴。

Abstract

[Objective]

The Baoji-Chengdu Railway is one of the crucial railway corridors connecting Southwest and Northwest China.However

the Baoji-Yangpingguan section remains a single-track railway with a capacity utilization rate of 93.3%

indicating that its capacity has reached saturation.Furthermore

the effective length of arrival-departure tracks in this section is only 650～700 m

and the traction tonnage is only 2600/3000 t

whi

ch is inconsistent with that of the connecting corridors.Freight trains need to undergo locomotive attachment/detachment and axle adjustment operations at Qinling

Yangpingguan

Guangyuan

and other stations

resulting in inefficient transport organization.As cross-regional freight exchanges between Northwest China and Southwest China and between North China and Southwest China continue to increase during the study period

the need for capacity expansion and renovation of the Baoji-Chengdu corridor has become increasingly prominent.

[Methods]

Based on the existing problems

functional positioning

and transport demand of the Baoji-Chengdu Railway

this study investigated construction schemes for a high-capacity and high-standard corridor that met transport capacity requirements while ensuring safe and reliable operation.Considering the characteristics of different sections

a “hierarchical and segmented”research method was adopted

and three construction plans were proposed:singletrack capacity expansion

addition of a second track

and construction of a new double-track railway.The plans fully considered the impacts of geological hazards

made rational use of the existing railway

and were comprehensively compared in terms of engineering investment

transport organization

and transport capacity.

[Results]

The analysis showed that the plan involving construction of a new double-track railway from Baoji to Qinling

addition of a second track from Qinling to Yangpingguan

and extension of the effective length of arrival-departure tracks to 850 m had good compatibility with regional railway transport corridors

met transport demand during the study period

and required lower engineering investment.The plan provided a reference for the capacity expansion and renovation of the Baoji-Chengdu Railway and for improving the transport efficiency of the corridor.

[Conclusion]

The methods and results can provide guidance and references for similar studies.
