无砟轨道有轨电车路基基床结构探讨

Discussion on Subgrade Bed Structure of Ballastless Track for Tram

国内现代有轨电车建设尚处于起步、摸索阶段,路基设计无现行规范可执行,路基基床结构设计多参照国内铁路技术标准。对此,在理论分析基础上,结合国内在建(已建)的无砟轨道有轨电车项目工程建设经验,对路基基床结构进行探讨,并提出适合无砟轨道有轨电车项目的路基基床结构形式及填料要求。

The modem tram development in the country is still in the initial exploration stage, and there has no current specifications for the subgrade design, then in most cases, the bed structure design refers to the domestic railway technical standards. Thus based on the theoretical analysis and combined with the engineering construction experience from the domestic projects of ballastless track for tram, both under construction and completed, the subgrade bed structure was discussed, and the proper structure type and filling requirement thereof were proposed.
