我国四大干线提速列车牵引质量、运行速度、行车密度合理匹配的研究

Research on the Reasonable Match of Train Weight,Speed and Density on the Four Major Trunk Lines in China

本文根据四大干线的技术条件，论证了提速客货列车的牵引质量，运行速度，行车密度间的合理匹配。同时，提出了京广、京沪、京哈、陇海四大干线客货列车具体匹配方案及线路客货输运能力最大作为剖别条件的建议。

Based on the technical conditions of the four major trunk lines,this article demonstrates the rational match between hauled weight,operating speed and traffic density.It puts forward a proposal concerning the practical matching plan for passengenger and freight trains on the four major trunk lines.Taking maximum traffic capacity as the judging criterion.
