摘要
对比分析不同速度等级条件下八辆兼顾四辆编组列车车型的主要技术参数,研究该型编组列车在输送能力、追踪间隔、加速性能、定员设置等方面特性,以长株潭城际线路为例验证其公交化开行的技术优势。研究八辆兼顾四辆编组列车在国内的应用情况,分析多个子系统的技术可行性,构建列车成本经济计算模型,论证该型列车八辆编组与四辆编组条件下运营经济性。最后以广珠及佛肇城际为例,实证研究在一定客流高峰小时断面阈值范围内,列车开行对数及高峰断面客流变化下该型编组列车的技术可行性及经济性。研究结论可为客运需求快速变化条件下城际铁路项目运营中的列车编组决策提供参考。
This paper compares and analyzes the main technical parameters of 8-car and 4-car trains under different speed levels,and studies the characteristics of this type of train in terms of transportation capacity,tracking interval,acceleration performance and personnel setting.Taking Changsha-Zhuzhou-Xiangtan intercity train as an example,the technical advantages of bus type operation are verified.This paper studies the application of 8-car and 4-car trains in China,analyzes the technical feasibility of multiple subsystems,constructs the economic calculation model of train cost,and demonstrates the operation economy of this type of train under 8-car and 4-car configuration.Finally,taking Guangzhou-Zhuhai and Foshan-Zhaoqing intercity trains as an example,this paper empirically studies the technical feasibility and economy of this type of train with changes in train number and peak section passenger flow within a certain range of peak hour section threshold.The research conclusions can provide reference for train formation decision-makings in intercity railway project operations under the rapidly changing condition of passenger demand.
