四平至通化铁路扩能工程建设方案研究

Study on Construction Scheme of Siping-Tonghua Railway Capacity Expansion Project

随着区域经济的快速发展,四平至通化铁路的运输能力、运营质量等已经不能满足运输需求,亟需进行扩能改造。在阐述既有铁路概况及存在问题的基础上,结合区域路网现状及规划,考虑沿线地区铁路运量预测、远期发展和功能定位,提出单线格局扩能、双线格局扩能和三线格局扩能3大系列方案,在此基础上对160 km/h,200 km/h 2个速度目标值进行分析对比,推荐采用沿既有线增建二线扩能、速度目标值为160 km/h的客货共线双线格局方案,对类似山区干线铁路扩能改造建设方案具有重要参考价值。

As regional economy advances rapidly,the transportation capacity and operation quality of the Siping-Tonghua Railway can no longer meet the transportation demand,which is in urgent need of capacity expansion.In light of the general situation and problems of the existing railways,this paper studied the current situation and planning of the regional railway network.Considering the traffic volume forecast,long-term development and functional positioning of the areas along the railway lines,three plans for capacity expansion were proposed,including the single line pattern,the double line pattern,and the three line pattern.On this basis,two speed target values,160 km/h and 200 km/h,were analyzed and compared.It is recommended to build a second line for mixed freight and passenger train traffic along the existing lines for capacity expansion,at a target speed of 160 km/h,which provides a reference for capacity expansion of similar truck railways in mountainous areas.
