随着轨道及道床设计不断发展,轨道交通路堤结构上道床敷设方式逐步由碎石道床向整体道床上铺设无缝线路转变,根据梁轨相互作用的设计思想,对路基挡墙的设计提出了更高的要求。作者通过参加几条城市轨道交通路堤段的设计,总结出城市轨道交通路堤结构的设计特点及地基处理方法为今后设计提供参考经验。 With the continuous development of track and track bed design, the way of laying of track bed on the railroad traffic embankment structure gradually transforms the seamless track from the gravel track bed to the integral track bed. According to the design idea of ​​beam-rail interaction, the design of subgrade retaining wall is proposed higher requirement. By participating in the design of several urban rail transit embankment sections, the author summarizes the design features of the urban rail transit embankment structure and the foundation treatment methods to provide reference experience for future design.
