摘　　要：受轮轨关系、弓网关系、空气动力学及能耗经济性等因素制约,既有轮轨高速铁路难以实现进一步提速。高速磁悬浮铁路可以解决轮轨铁路存在的轮轨黏着、摩擦、振动和高速受流等问题,具有更高的提速潜力,近年来逐渐成为地面交通领域的研究热点。以我国和日本、德国、美国等代表性国家为例,从技术装备、线路建设等方面介绍了不同国家高速磁悬浮铁路的发展现状,分析了未来世界高速磁悬浮铁路的发展趋势。总体上看,高速磁悬浮铁路将向速度更高、成本更低、技术更实用化等方向发展,结合低真空管道技术的高速磁悬浮铁路具有良好的发展前景。Restricted by the wheel-rail interaction,pantograph-catenary interaction,aerodynamics and energy consumption efficiency,it is difficult for the existing wheel-rail high speed railways to further speed up.The high speed maglev railways can solve the problems such as wheel-rail adhesion,friction,vibration and high speed current collection in the wheel-rail railways.With higher speed-up potential,the high speed maglev railways have gradually become a research hotspot in the field of ground transport in recent years.Taking China,Japan,Germany,the United States and other representative countries as examples,the paper introduces the development status of the high speed maglev railways in different countries in such aspects as technical equipment and railway construction,and analyzes the development trend of the high speed maglev railways in the future.On the whole,the high speed maglev railways will progress in the trends of higher speed,lower cost and more practical technology.The high speed maglev railways in combination with the technology of low vacuum tube enjoys a promising future.
