复杂地形及控制条件下的城市道路选线方案——以昆明市西山区兴团大道为例

Route Selection Scheme of Urban Roads under Complex Terrain and Control Conditions:Taking Xingtuan Avenue,Xishan District,Kunming City as an Example

随着城市边界的扩展,越来越多的城市道路需要在复杂地形及控制条件下进行布置,道路的选线是其设计的一个重要环节,而路线的合理性则直接关系到道路的质量、工程造价及安全和稳定性。现以西山区兴团大道为案例,从线路衔接点选择、断面布置、技术标准、安全性、控制条件的处理等多角度,进行选线方案的研究,为山区城市干路选线方案提供参考。

With the expansion of urban boundaries,more and more urban roads need to be arranged under complex terrain and control conditions.Road route selection is an important part of their design,and the rationality of the route is directly related to the quality,engineering cost,safety,and stability.Taking Xingtuan Avenue in Xishan District as a case study,this paper conducts research on route selection schemes from multiple perspectives such as line connection point selection,section layout,technical standards,safety,and control conditions,providing reference for route selection schemes for urban trunk roads in mountainous areas.
