摘　　要：在铁路智能选线中,线路走向通道规划是一个至关重要的步骤,是后续线路方案设计的基础。针对分析总结现有线路走向通道规划方法的优缺点,提出基于代价图的铁路线路走向通道智能规划方法。基于线路技术标准进行地形快速探查,构建桥隧高代价面域;基于各类面域的边界特征线,通过三角剖分构建无向图,并形成代价图;基于差异演化算法,计算最优代价参数集;基于代价图,使用改进的Dijkstra算法生成多样化走向通道;基于走向通道,进行站位的智能推荐。应用验证结果表明,该方法能够快速生成多个线路走向通道,为线路方案决策提供参考,有效提高设计效率。During intelligent railway line selection,alignment corridor planning is a crucial step and the basis for subsequent line scheme design.Aiming at analyzing and summarizing the advantages and disadvantages of existing alignment corridor planning methods,this paper proposes an intelligent railway alignment corridor planning method based on cost diagram.This paper carries out rapid terrain exploration based on line technical standards to acquire high-cost surface areas of bridges and tunnels;an undirected graph is developed through triangulation based on boundary feature lines of various surface areas,and a cost diagram is formed;the optimal cost parameter set is calculated based on differential evolution algorithm;diversified alignments corridors are generated by using improved Dijkstra algorithm based on cost diagrams;intelligent recommendation of station locations is made based on alignment corridors.The application verification results show that the method can quickly generate multiple alignment corridors,which provides references for line scheme decision-making and effectively improves design efficiency.
