摘要
中国重载铁路存在重去空回的运营实际,造成一定的运力浪费,部分线路采用双向重载运输模式来缓解此情况。为使得铁路运营部门明确该模式带来的效益,研究了重载铁路线路双向运输效益评估方法,通过“双向运输综合效益”指标,反映经济、环境效益双方面效益情况,进而以反向运输环节为重点,设置算例来研究反向运量规模、货物品类对双向运输综合效益的影响。研究表明,在算例条件下,反、正向的运量比值从2%提升至20%,双向运输综合效益增长幅度为5.25%。反向运量占正向运量比重分别为2%、20%时,当反向运输中高附加值货物占比从5%提升至30%,双向运输综合效益相应地上涨0.43%、4.18%。综合来看,重载铁路运营部门可拓展双向重载运输业务覆盖范围,并通过与途经地区有货运需求的企业合作等策略,保证稳定的反向货源,以提升双向综合效益,利于双向均衡运输,促进综合效益最大化。
Most of China’s heavy-haul railways face the issue of unbalanced volumes,resulting in a certain amount of wasted transportation capacity.The mode of two-way transportation of heavy-haul railway is carried out.An evaluation method of heavy-haul railway’s two-way transportation benefits was proposed so that the railway operation department can clarify this mode’s benefits.The index of“comprehensive benefits of two-way transportation”including economic and environmental benefits,was used to determine the transportation benefits.The numerical example was designed to examine the effects of reverse transportation volumes and cargo type on two-way transportation benefits.The results show that,when the proportion of reverse and forward transportation volumes increases from 2%to 20%,the comprehensive benefits of two-way transportation increase by 5.25%.When the proportion of reverse and forward transportation volumes is from 2%to 20%,the proportion of high-value-added goods in reverse transportation increases from 5%to 30%,and the total benefits of two-way transportation reach 0.43%and 4.18%,respectively.On the whole,heavy-haul railway lines in China can develop two-way transportation mode,and ensure a stable reverse supply of goods through strategies such as cooperating with enterprises that have freight needs in the transit area,so as to promote comprehensive benefits and realization of two-way transportation.
