| 摘 要： | 现代铁路选线设计特别注重复杂地质条件下的线路方案设计及比选问题,而地质问题涉及因素众多,线路方案决策具有较强综合性特点。利用GIS的数据管理和空间分析决策功能可以实现线路方案行经区域不良地质特性的有效表达和提取,并且可以分析出不同线路之间行径区域的不良地质情况对比。通过利用ArcGIS构建不良地质区域铁路走向辅助决策的层次分析模型,并且结合层次分析法,实现基于地质选线的方案优选。

| Abstract: | The modern design of railway lines was with particular emphasis on the design of railway line scheme under complicated geological conditions and selection. The geological problems involve many factors so the railway line scheme of the decision making has the characteristic of strong comprehensiveness. By using the function of data management, spatial analysis and decision-making of GIS(Geographic Information System), it could be implemented the effective expression and extraction for bad geological characteristic of the regional railway lines scheme, analyzed the bad geological situation comparison between different railway lines. The article used ArcGIS to construct the analytic hierarchy process model of railway auxiliary decision-making in the bad geological area and implement the railway line selection based on the geological combined with the analytic hierarchy process. |
