跨座式单轨系统限界体系转换研究

重庆轨道交通较新线是我国首次从日本引进的跨座式单轨系统,其限界体系沿用日本标准,属"二限界"体系,与我国地铁限界标准在体系、参数与应用上存在较大差别。文章阐述了跨座式单轨限界由日本"二限界"转换为中国"三限界"体系的思路、方法和参数取值,从而建立了我国跨座式单轨交通限界体系。研究成果纳入了规范,为工程设计提供了标准和依据。

Study of gauge system conversion of straddled monorail transit

Straddled monorail transit system is introduced to Chongqing Rail Transit Jiaoxin Line from Japan for the first time ever in China.It adopts Japanese standard dual-gauge system,which is very much different from Chinese metro gauge standard in terms of coordinates,parameters and application.This paper presents the idea,method and reference data for gauges conversion of straddled monorail system from Japanese dual-gauge system to Chinese trio-gauge system,from which we established our own straddled monorail transit system.Meanwhile,relative standards are created upon the study results,which provide standard and basis for engineering and design.
