摘　　要：研究目的:通过对已开通中低速磁浮项目的研究,分析得出其具有小半径、选线灵活、爬坡能力强等特点;但既有项目工程条件单一,以桥梁工程为主,不具有广泛代表性。清远市磁浮旅游专线走行于城市规划区,多次与既有铁路、高速铁路、高等级公路交叉;工程条件复杂,类型齐全,包含大跨桥梁、双线隧道、三线隧道、高边坡路基等工程,其线路方案研究对中低速磁浮铁路具有更广泛的代表性。研究结论:(1)利用中低速磁浮铁路小半径、选线灵活的特点,贴合城市既有主干道通行以减少房屋拆迁,线路方案可以更加契合城市规划;(2)利用磁浮铁路爬坡能力强的特点,采用大坡度下穿既有交通以降低桥梁高度,降低施工、运营风险及工程造价;(3)本文研究对中低速磁浮铁路勘察设计、特定区域轨道交通的制式比选具有参考借鉴作用。Research purposes: Through the research on the opened medium and low speed maglev projects, the analysis shows that it has the characteristics of small radius, flexible route selection and strong climbing ability. However, the engineering conditions of existing projects are single, mainly bridge engineering, which is not widely representative. Qingyuan maglev tourism railway runs in the urban planning area, crossing with the existing railway, high-speed railway and high-grade highway for many times. The engineering conditions are complex and the types are complete, including long-span bridge, double track tunnel, three track tunnel, high slope subgrade and other projects. The research on the route scheme is more representative for the medium and low speed maglev railway.Research conclusions:(1)Taking advantage of the small radius and flexible line selection of medium and low speed maglev railway, the route scheme can be more suitable for urban planning, which is suitable for the existing main road passing in the city to reduce the house demolition.(2)Taking advantage of the strong climbing ability of maglev railway, in order to reduce the height of the bridge, reduce the construction and operation risk and project cost, large slope is used to cross the existing traffic.(3)The research in this paper can be used for reference in the survey and design of medium and low speed maglev railway and the comparison and selection of rail transit system in specific areas.
