关于铁路枢纽联络线与疏解线的设计分析

Analysis on the design of connecting and distribution lines at railway terminals

铁路联络线和疏解线是铁路路网不可缺少的组成部分,线路不长但用途很大,在新线设计尤其是枢纽设计中经常遇到。联络线的标准一般应与相邻线的标准一致;疏解线的标准由于其特殊性,在设计规范中规定了最小曲线半径和最大纵坡。站场设计手册对枢纽的疏解方式做了一些归类与分析,但设计者只知道这些还远远不够。随着枢纽引入线路的增多,联络线与疏解线会越来越复杂,既涉及到如何节省工程投资,更涉及到运输安全、质量与效率。分析铁路枢纽联络线与疏解线的设计方法,以便更好地设计这类线路。

Connecting and distribution lines are indispensable part of the railway net. The length of the two kinds of lines is not long, but their roles are important. The lines often appear in the design of new lines, especial terminals. The standard of a connecting line is the same as an adjacent line. Because of the particularity of the standard of distribution lines, there are the least curve radius and the largest longitudinal slope in design specifications and some classification and analysis on the distribution modes of terminals in the station and field design manuals. It is not enough for designers. Due to the increase of lines leading to terminals, connecting and distribution lines become more and more complicated, relating to saving investment and safety, quality and efficiency of transport. In order to design better the lines, the article analyses the design method of connecting and distribution lines of terminals.
