双线自闭区段旅客列车扣除系数数值分析

The Analysis of Coefficient of Passenger Train Removal on Double Track Railway with Automatic Block Systemn

正确分析和确定双线自动闭塞区段旅客列车的扣除系数,是计算和研究既有铁路干线通过能力的关键步骤。以区间不均等程度、客货列车速度比、货车追踪间隔3个因素对旅客列车扣除系数的影响关系为研究对象,通过确定3个因素的变化范围设计了旅客列车组运行图铺画的方案,采用模拟和图解的方法,利用计算机编图软件铺画各方案,并计算出每个方案对应的扣除系数。研究得到扣除系数随每个因素的变化规律以及完整的扣除系数表。

Analysising and determining the Coefficient of Passenger Train Removal on Double Track Railway with Automatic Block Systemn correctly is a committed step to study existing railway lines＇carrying capacity.This paper made interval unequality degree, Speed ratio of Passenger Train and goods train as reasearsh objects,then designed the plans of train chart drawing throuth the variation range of the three factors,using the map compilation software to draw plenty of train charts,then calculated removal coefficient of every plan, Finally,this paper got the change law of removal coefficient on every factor and a table of removal coefficient.
