摘　　要：随着"一带一路"合作倡议的推进,云南省铁路从全国路网的"终端末梢"逐步转变为"前沿枢纽"。为尽快解决广大通道线路标准低、运输能力短缺的问题,通过分析广大通道功能定位及广大单线铁路存在问题,结合广大单线铁路改造方案目标,在延长到发线有效长、提高牵引定数方面提出4个改造方案。经综合比选,推荐采用电力牵引、将楚雄西-大理到发线有效长延长至650m方案,极大地提升广大通道的运输能力,促进滇西地区经济的发展。The progress of the Belt and Road Initiative has changed Yunnan’s railway from the“End Terminal”to the“Hub in the Front”.To solve the problems of poor track quality and low capacity of the Guangtong-Dali corridor as soon as possible,this paper first analyzes the functions and orientation of Guangtong-Dali Corridor and the existing problems of Guangtong-Dali of singletrack railway.And considering the goals of Guangtong-Dali Single-track Railway reconstruction scheme,four reconstruction plans are proposed from the aspects of extending the sufficient length of arrival/departure tracks,increasing the traction tonnage,etc.After an in-depth comparison,it is recommended to adopt the plan of electric traction and extending the effective length of arrival/departure tracks of Chuxiong West-Dali section to 650 m.This result will significantly increase the capacity of the corridor and further promote the economic development of Western Yunnan.
