摘　　要：磁浮试验线是以进行实际运行时磁浮列车的各种工况试验为目的,线路平面设计包括反向曲线、同向曲线、最小夹直线等技术要素,同时能满足最高速度160km/h(远期预留200km/h)的运行试验要求(运行时间不小于10S)。根据周边地形地貌条件、道路和厂区场坪标高、车站和道岔设置要求以及试验线试验要求等因素确定本次试验线纵断面设计方案;试验线最小曲线半径和缓和曲线长度根据线路不同地段所能达到的最高时速计算确定;运用运动学公式,经理论分析计算及行车模拟,对试验线线路长度进行检算,最终确定试验线最合理长度和平、纵断面设计。The maglev test line is for the purpose of carrying out various working conditions test of maglev train in actual operation.The horizontal alignments design includes the reverse curve,the same direction curve,the minimum intermediate straight line and other technical factors,it also must meet the test requirements (sustaining time is not less than 10 s)at the maximum speed of 160 km/h (forward reservation 200 km/h).According to the surrounding topography and landform conditions,road and station yard elevation,station and turnout setting requirements,as well as requirements of the test line and other factors,the test line vertical alignments design plan is determined.The minimum curve radius and the length of the transition curve are determined based on the maximum speed that can be achieved in different sections of the line.Using the kinematic formula,the calculation of the length of the test line is carried out by theoretical analysis and traffic simulation,and finally the reasonable length as well as horizontal and vertical alignments design of the maglev test line are determined.
