摘　　要：[目的]针对当前市域(郊)铁路系统制式选择较为单一、工程投资较大、地下线占比较高等问题,分析中低速磁浮线在市域(郊)线路中的适应性,为市域(郊)线路发展提供多样化的系统制式选型。[方法]介绍了市域(郊)铁路的功能定位及中低速磁浮线的技术特征,结合市域(郊)铁路技术要求,从线路适应性、最高运行速度、环境协调性、运能适应性、互联互通及资源共享、综合能耗、工程投资等方面对中低速磁浮线与轮轨线路进行了详细对比分析。[结果及结论]研究结果表明:中低速磁浮线在线路适应性、环境协调性、乘坐舒适性以及工程投资等方面具有独特优势,非常适应于地形起伏较大、城区线路较长、服务范围相对独立、客流规模为中运量等级的市域线路。[Objective]Addressing the current issues of relatively limited system choices,large engineering investment,and high proportion of underground lines,the adaptability of medium-low speed maglev lines in city(suburban)railway is analyzed,and diversified system choices are provided for city(suburban)railway development.[Method]The functional positioning of city(suburban)railway and the technical characteristics of medium-low speed maglev lines are introduced.Combining with the technical requirements of city(suburban)railway,a detailed comparative analysis is conducted between medium-low speed maglev lines and wheel-rail lines from aspects including line adaptability,maximum operational speed,environmental compatibility,transportation capacity adaptability,interoperability and resource sharing,comprehensive energy consumption,engineering investment.[Result&Conclusion]Research results show that medium-low speed maglev lines have unique advantages in adaptability,environmental compatibility,ride comfort,and engineering investment,hence highly suitable for city railway lines characterized by significant terrain variations,longer urban routes,relatively independent service areas,and moderate passenger traffic volume.
