摘　　要：多年来铁路智能选线技术研发已取得重大进展,但由于铁路选线区域广、影响因素多、多专业综合性强等原因,智能选线研发难度大,应用的效率效果尚未达到广泛推广,因此,亟需找准重点,分步突破,以适应当前智能高速铁路2.0科技攻关等相关要求。本文提出大场景地形桥隧高代价区域自动探查、边权重灵活赋值比选的代价图构建、基于代价图的线路通道智能搜索、基于差异演化算法的线路方案平纵横自适应优化、线路平纵横实时联动GIS选线调优方法,实现了走向通道智能搜索→线路方案拟合优化→人机协同联动优化的铁路智能选线系统研发。经实例验证,采用上述关键技术、分步实施的铁路智能选线系统执行效率高、效果理想,可为铁路智能选线研发提供有益参考。Significant progress has been made in the research and development of intelligent railway line selection technology over the years.However,due to the wide range of railway line selection areas,multiple influencing factors,and strong multidisciplinary nature,the research and development of intelligent line selection is difficult,and the efficiency and effectiveness of its application have not yet allowed for widespread promotion.Therefore,it is urgent to identify the key and difficult points of intelligent line selection,break through them step by step,and adapt to the relevant requirements of the current intelligent high-speed rail 2.O technology research and development plan.We have proposed a cost map construction method for automatic exploration of high cost areas in large-scale terrain bridges and tunnels,flexible assignment and comparison of edge weights,intelligent search of route alignment based on cost maps,adaptive optimization of route plans based on differential evolution algorithms,and real-time linkage GIS route selection and optimization methods for route plans.This has enabled the development of a railway intelligent route selection system that includes intelligent search of route alignment,fitting optimization of route plans,and human-machine collaborative optimization.Through practical examples,it has been verified that the railway intelligent line selection system implemented step by step using the above key technologies has high execution efficiency and ideal results,which can provide useful reference and inspiration for the research and development of railwayintelligent line selection.
