市政道路路线设计探讨——基于贵阳市太金线工程实例

Discussion on Design of Municipal Road Route——Based on Example of Taijin Line Project in Guiyang

市政道路路线设计较公路设计复杂,道路选线过程中需按照城市整体规划布设,同时严格遵守国土空间“三条红线”控制,减少拆迁,合理掌握应用技术指标,遵循“以交通功能需求为前提,满足城市总体规划,结构安全可靠,投资造价合理,景观环境优美”的设计原则。本文以贵阳市太金线的路线设计为例,探讨市政道路路线设计的技术难点与要点。

The design of municipal road routes is more complicated than that of highways.During the process of road route selection,it is necessary to follow the overall planning of the city,and at the same time,strictly abide by the“three red lines”control of land and space,reduce demolition,reasonably grasp the application technical indicators,and follow the design principles of“take traffic function requirements as the premise,meet the overall planning of the city,ensure safe and reliable structure,reasonable investment cost,and beautiful landscape environment”.This article takes the route design of Taijin Line in Guiyang City as an example to discuss the technical difficulties and main points of the route design of municipal roads.
