| 摘 要： | 公路与城市道路技术指标有差别，选线方案需要综合考量。以某市绕城道路为研究对象，采取现场调查的方法对沿线主要工程地质问题进行梳理，提出了山区城市道路选线原则。调查发现:研究区工程地质问题突出，不良路段分布广泛。在路线比选过程中，遵循环境选线和安全选线的原则，通过对不良地质条件路段的方案对比和优化，总结高原地区公路选线的经验。成果对于西部高原山区城市道路选线设计具有参考意义。

Study on Route Selection of Ring Road and Urban Road in a Plateau Mountain Area |
| |
| Abstract: | The technical indexes of highway and urban road are different, so the route selection scheme needs to be considered comprehensively. Taking the ring road in a city as the research object, the main engineering geological problems along the road are sorted out by the method of field investigation, and the principle of route selection for mountain city road is put forward. It is found that the engineering geological problems are prominent and the bad sections are widely distributed in the study area. In the course of route comparison and selection, following the principles of environmental route selection and safety route selection, the experience of highway route selection in plateau area is summarized by comparing and optimizing the schemes of sections with bad geological conditions. The results are of reference significance for urban road alignment design in western plateau mountainous areas. |
