In this paper , the research is based on the constructive need of the magnetic levitation railway test line in shanghai . using large - scale current finite element software , the author comparatively analyzes several structure types of bridges fitted for the high - speed magnetic levitation railway lines . the main purpose is trying hard to provide reference for the decision - making of the long magnetic levitation railway lines 本文结合上海磁悬浮铁路试验运营线的工程建设需要，利用大型通用有限元分析软件，对适用于高速磁悬浮铁路线路轨道梁的各种桥梁结构型式进行了分析、比较研究，力图为我国长大磁悬浮铁路线路的决策提供必要的参考依据。
The detailed contents are as follows . through comparatively analyzing design demands in the specifications of countries in the world for the high - speed railway bridges , studying all sorts of structure types of the guideway girder adopted in some country , and summarizing the design outlines of the magnetic levitation guideway girder , the author bring forward a new - style structure of guideway girder : composite steel - concrete structure 具体研究内容有：通过分析对比世界各国高速铁路桥梁的设计规范对高速铁路桥梁的设计要求，研究各国各种磁悬浮试验线路所采用的轨道梁结构型式，总结磁悬浮铁路轨道梁的设计要点，提出了一种新型的轨道梁结构型式：钢?混凝土组合结构轨道梁。
Among railway line ' s plane design parameter , the minimum radius of curve , transition curve ' s type and length , straight line between two curves , centre - to - centre distance of track are key factors which confine railway to bringing up speed , moreover these factors among maglev railway request even more strict 由于高速磁悬浮铁路采用了非接触式的行车技术，舒适性将得到很好的改善。铁路线路平面设计参数中，最小曲线半径、缓和曲线长度、夹直线长度、线间距离是限制列车速度的关键因素，高速磁浮铁路同样如此。
Presently , the feasibility studies of long high - speed magnetic levitation railway lines are on the point of start - up in our country . the construction of the long magnetic levitation railway lines cannot depend on the introduction of the entirely magnetic levitation technology . from the situation of our country economy , we must tackle the key problem of the innovative technology on the base of assimilating the foreign magnetic levitation technology 目前，我国长大磁悬浮线路的可行性研究即将启动，其建设不能靠全部引进国外高速磁悬浮列车系统，必须在消化、吸收国外磁悬浮列车技术的基础上，从我国的具体经济条件出发，开展创新性科技攻关，这将对建立我国合理、经济的高速磁悬浮铁路系统具有十分重要的现实意义。
