摘要
大准铁路是西煤东运的重要通道,经济快速发展极大地促进了煤炭需求的增长,大准铁路常年处于满负荷运输状态。为了进一步释放大准线运输能力,亟须对线路中单线区段进行扩能改造。本文基于大准线线路特点,同时考虑实际运输需求,通过理论计算确定了限制大准线单线区段运输能力的关键区间。在此基础上,从增加具有万吨列车到发线的车站数量、增加万吨列车到发线数量、部分或全部区段进行增二线改造等多个角度提出扩能改造方案,以期为大准铁路即时和长远发展提供有力的技术支持。
The Dazhun railway is an important route for coal transportation in the western region.The rapid economic development has greatly promoted the increase in demand for coal,and the Dazhun line has transported at full capacity for a long time.Therefore,transport capacity expansion projects in the single line sections need to be carried out urgently to increase the transport capacity of the railway.According to the track features and traffic volume,the section limiting the transport capacity has been identified.Furthermore,several plans for expanding the transport capacity have been proposed,including increasing the number of stations with receiving-departure tracks for 10000-ton trains,increasing the receiving and departure tracks,and the construction of double-tracks.This research provides technical support for the immediate and long-term development of the Dazhun railway.
