基于GIS技术的山地道路竖向设计方法

The vertical design method for mountain roads based on GIS technology

山地道路竖向设计,需三维统筹设计平面与竖向,GIS的信息处理与分析功能,可提供较客观、可视化的数据支持,辅助设计。以M市临湖路设计为例,探讨了GIS运用于道路竖向设计的方法,并详述GIS工具应用于道路起始点高程确定、平面选线、坡向、控制点高程设计和优化等方面的具体流程,以期对普遍提高山地道路设计质量有一定借鉴作用。

The vertical design of mountainous roads requires a three-dimensional coordinated design of both the plane and vertical,the GIS information processing and analysis functions can provide objective and visual data support to assist in the design.Taking the design of Linhu road in M City as an example,this paper explored the method applied of GIS application in road vertical design,and elaborated in detail the specific process applied of GIS tool application in road starting point elevation determination,plane route selection,slope direction,control point elevation design and optimization and other aspects,in order to have a certain reference value for improving the design quality of mountain road in general.
