对高速磁浮线路最大横坡选择的探讨

摘要

结合高速磁浮线路自身的技术特点,对高速磁浮线路最大横坡的选择进行了探讨,并对横坡的大小与曲线半径、曲线长度、工程费、舒适度等之间的关系进行了分析.分析结果表明,最大横坡取9°与12°相比,对最小曲线半径值和房屋拆迁费的影响不大,但从提高旅客舒适度和节省轨道梁制造成本等角度考虑,最大横坡应不大于9°为宜.%Based on their technique characteristics of high speed maglev lines, this paper discusses the maximum angle selection of transverse gradient for high speed maglev line design and analyzes the relations between the angle values of the transverse gradient, the curve radius, the curve length, the engineering cost, and the passengers' comfort degree, etc. The analysis results show that in comparison with selecting 12° maximum angle of transverse gradient, selecting 9° maximum angle of transverse gradient has little impact on the minimum curve radius value and the house demolition charges. But considering increasing passenger comfort degree and saving track beam manufacturing cost, the maximum angle of transverse gradient should not be more than 9 °.
