公路与城市道路路线设计主要指标对比

Comparison of Main Indexes of Highway and Urban Road Route Design

本文对比分析现行JTG D20-2017《公路路线设计规范》和CJJ 193-2012《城市道路路线设计规范》中平面、纵断面内容,总结公路与城市道路路线设计方法、脉络、异同,发现两者设计思想一脉相承,但是在线形设计细节的规定上各有侧重。总结两本规范异同,可以帮助在设计中相互印证、相互借鉴,提升设计质量。

By comparing and analyzing contents of plan and profile in the Design Specification for Highway Alignment(JTG D20-2017)and Code for design urban road alignment(CJJ 193-2012),the paper summarizes the design method,context,similarities and differences between highway and urban road.It is found that the two design ideas come down in one continuous line,however,there are different emphases on the details of linear design.The comparison of the design indexes of the two specifications can help to confirm and learn from each other in the design,thus improving design quality.
