中低速磁浮制式市域(郊)铁路发展若干问题的分析与思考

Analysis and Thinking on Several Problems Concerning Development of Medium and Low Speed Maglev Urban Railway

近年来我国市域(郊)铁路建设呈加速发展态势,中低速磁浮制式市域(郊)铁路具有较大发展潜力,系统性分析思考相关问题,对我国市域(郊)铁路科学和高质量发展具有重要意义。总结市域(郊)铁路基本特征,分析中低速磁浮制式技术特点,得出中低速磁浮制式适用于市域(郊)铁路并较轮轨制式有一定技术经济优势的结论。基于当前市域(郊)铁路建设发展现状和财政支撑问题,认为中低速磁浮制式所具有的技术经济优势更有利于实现建设运营的降本增效,中低速磁浮制式面临难得的发展机遇,但同样也面对诸多挑战。对此,以可持续发展为目标,提出广泛凝聚共识、做好顶层规划、科学设计模式、持续技术创新等发展策略建议,以及构建空间、模式、技术正向循环并不断深入创新的基本发展路径,为中低速磁浮制式市域(郊)铁路建设发展相关决策提供参考。

The recent years has seen accelerating the development of urban railway,with medium and low speed maglev urban railway enjoying great development potential.Therefore,a systematic analysis and thinking on several problems concerning development are of great significance to scientific and high-quality development of urban railway.This paper summarized the general features of urban railway,analyzed characteristics of maglev system,and concluded that medium and low speed maglev system is applicable to urban railway,with some technical and economic advantages over the wheel rail system.For the status quo and financial problems concerning the development of urban railway,this paper considered the technical and economic advantages of medium and low speed maglev system are more beneficial to reducing cost and increasing efficiency in construction and operation,which has brought exciting opportunities for the medium and low speed maglev system,while leaving it under many challenges.Amid the commitment to sustainability,this paper gave four suggestions on development strategy which involves building extensive consensus,making top-level planning comprehensively,designing relevant models scientifically and making technological innovations continuously,and generally charted the course that is about building a positive cycle of space,models,and technologies,and deepening innovation efforts,which can be used as a reference for the relevant decision-making on the development of medium and low speed maglev urban railway.
