成都现代有轨电车路基设计特点探讨

Discussion on the Design Characteristics of Modern Tram Subgrade in Chengdu

近年来,现代有轨电车作为一种新型城市轨道交通方式,一般敷设在市政道路路中或路侧,与地铁、轻轨、高铁设计还是有差别。基于此,在现有路基设计的理论基础上结合成都有轨电车项目工程情况,对现代有轨电车的路基标准横断面、工后沉降、过渡段、排水设计、道路搭接等技术要点进行了探讨与总结,可为今后类似工程设计提供参考。

In recent years,modern trams,as a new type of urban rail transit,are generally laid on municipal roads or roadsides,and are different from subway,light rail and high-speed rail.Based on this,the existing roadbed design based on the theory of combining chengdu trams project engineering situation,the subgrade of modern tram standard cross-section,postconstruction settlement lap,transition section and drainage design,road,etc.This paper discusses the main technical points and summary,can be designed to provide the reference for future similar projects.
