摘　　要：山地轨道爬坡能力强,爬坡速度快,建设成本低。本文在系统总结国内外齿轨交通研究现状的基础上,对齿轨铁路的轨道结构方案开展设计研究,提出三种适用于山地轨道的轨道结构形式——无砟轨道结构方案、聚氨酯固化道床结构方案和有砟轨道结构方案,给出其主要技术参数,并从运营条件及经济性两方面分析了三种方案的优缺点。结果表明:无砟轨道结构的稳定性最好,聚氨酯固化道床结构次之,有砟轨道结构经济性最优。一般地段推荐采用有砟轨道结构方案,较大坡道地段推荐采用无砟轨道结构方案。The mountain track has strong climbing ability,fast climbing speed,and low construction cost.Based on a systematic summary of the current research status of toothed rail transit at home and abroad,this article conducted a systematic design study on the track structure scheme of toothed rail railways,proposed three types of track structure forms suitable for mountain tracks,which are structural schemes for ballastless track,polyurethane cured ballast bed,and ballasted track,provided its main technical parameters and analyzed the advantages and disadvantages of three solutions from the perspectives of operating conditions and economy.The results indicate that the stability of ballastless track structure is the best,followed by polyurethane cured ballast bed structure.The ballasted track structure has the best economic efficiency.It is recommended to adopt a ballasted track structure scheme for general section and to adopt the ballastless track structure scheme for sections with larger slopes.
