摘　　要：通过对选取的45条客货共线铁路共69个区段2015—2017年3个年度客货行车量统计样本资料分析,找出我国客货共线铁路运营现状特点及存在的不足。结合目前客货共线铁路分级标准及样本数据,采用多项指标划分法,从客货运量、旅客列车设计速度和线路意义及路网作用等方面对客货共线铁路分级标准进行评价与研究。最终考虑原规范中Ⅲ级、Ⅳ级铁路技术标准差异不大,建议将Ⅲ级、Ⅳ级铁路合并为一级,客货共线铁路分级由四级调整为三级,并建立了综合运量、速度、路网意义等评价因素的客货共线铁路分级定量评价模型。可避免常规分级评价中定性评价方法导致主观因素干扰明显,以及因某一评价因素过分突出而引起评价误差等问题,对客货共线铁路分级有一定参考价值。This paper selected 45 passenger and freight railway,a total of 69 sections.Based on the statistical analysis of passenger and freight traffic in 2015—2017,the paper found out the current situation and disadvantages of mixed passenger and freight railway in China.Combined with the current mixed passenger and freight railway classification standards and sample data,the multi-index partition method was adopted to evaluate and research the classification standards of mixed passenger and freight railway from the aspects of passenger and freight volume,the design speed of passenger trains,the significance of railway lines,and the function of railway network.Finally,as the difference between levels III and IV railway technical standards is not great in the original specifications,it is suggested that class III and IV railways should be merged into one class,and the mixed passenger and freight railway classification should be adjusted from four levels to three levels.Besides,the quantitative evaluation model of mixed passenger and freight railway was built,which integrated the evaluation factors such as traffic volume,speed,and the significance of the railway network.In this way,problems like the subjective interference caused by qualitative evaluation methods and evaluation error caused by overly prominent evaluation factors can be solved,and certain reference values for mixed passenger and freight railway classification can be provided.
