AI Technical Summary
Technical Problem
In railway design on steep slopes, existing technologies are complex and time-consuming to calculate, and do not take into account railway clearance constraints, resulting in low design efficiency.
Method used
A multi-branch tree route search algorithm is adopted, combined with intelligent search parameters and DEM grid elevation files, to generate a global feasible path tree from the starting point to the ending point, and to perform clearance constraint detection to generate a horizontal and vertical route scheme.
Benefits of technology
This reduced the amount of data processing, improved the efficiency of route generation, and ensured that the generated route plans met design standards and clearance requirements.

Abstract
本发明涉及铁道施工技术领域，具体涉及一种紧坡地区路线生成方法、系统、设备、介质及程序产品。紧坡地区路线生成方法包括以下步骤：获取道路选线设计标准和研究区域的DEM格网高程文件；根据道路选线设计标准确定智能搜索参数；生成起点至终点的全域可行路径树；从终点依次回溯路径节点至起点，梳理出可行三维路径集；利用单条路径的三维节点坐标，生成对应的平纵面路线方案。本发明通过多叉树线路搜索算法，构建起点至终点的全域可行路径树，无需遍历研究区域，降低了数据处理量，提高了方案生成效率，并且可以通过对道路选线设计标准进行约束，确保生成可行方案。
