摘要
真空管道高速交通作为一种新型的交通运输系统,已成为世界各国研究的热点和行业重点发展方向。以目前国内外文献主要围绕的真空管道压力、阻塞比、气动阻力、磁浮体系和车体等方面行业现状的研究为基础,结合中低速、高速磁浮设计规范及设计理念,对桥梁结构影响较大的管道结构、管道材料、温度荷载、疲劳荷载等低真空管道高速磁浮铁路桥梁结构中存在的主要问题进行了初步探讨。
As a new type of transportation system,the vacuum tube high-speed traffic has become a research hotspot and a key development direction in the world.The vacuum tube pressure,blockage ratio,aerodynamic drag,maglev system,vehicle body,etc.were mainly studied by domestic and foreign scholars at present.So combined with the medium and low speed maglev transit,high-speed maglev transportation design specification and design philosophy,the main problems such as tube structure,material,temperature load and fatigue load of the bridge structure in low vacuum tube high-speed maglev railway were preliminarily discussed.
