摘要
磁浮轨道交通技术能够摆脱轮轨关系的束缚,近年来进展显著,为高速磁浮轨道交通系统的应用提供可能。通过提炼时速600 km以上超高速磁悬浮的技术特征,探讨其市场、成本、投资等经济特性,研究分析超高速磁浮轨道交通系统在实际投入运营时,亟待解决的安全风险、选线及试验线建设困难、客流需求不足、运输能力有限、经济性不佳等方面难点,并对下一步超高速磁浮系统的发展提出小型化、特殊应用、借鉴航空、扩大研究范围等建议。分析认为技术理论问题虽逐步突破,但需要理性对待超高速磁浮交通系统的建设,判断其短期投入商业化运营可能性较低。
Maglev rail transit technology is able to get rid of the wheel-rail relationship and has made remarkable progress in recent years,which provides the possibility for the application of high speed maglev transportation.By refining technical characteristics of the ultra-high speed maglev above 600 km·h^(-1) and discussing its economic characteristics such as market,cost,and investment,the difficulties in safety,line selection,test lines,passenger demand,transportation capacity and economy which need to be solved for ultra-high speed maglev system application are analyzed.This paper proposes miniaturization,special applications,reference to aviation and technology advancement for further development.The results show that although technical theoretical issues are being gradually broken through,the construction of ultra-high speed maglev transportation needs to be treated rationally,and it is less likely to be put into practical application in the short term.
