摘　　要：咽喉区道岔分组不仅是运用利用率计算法查定铁路车站咽喉通过能力的必要步骤,还是车站进路选择、股道运用等行车技术作业的关键环节。为解决当前自动分组方法不能有效解决复杂咽喉区非水平方向布置道岔的分组问题,将咽喉区道岔分组问题抽象为有向图中点的归属问题,构建咽喉有向图模型和道岔分组有向图模型,设计二阶段法对模型求解。第一阶段识别平行进路,目标是基于咽喉有向图运用DFS算法识别并生成平行进路对全集;第二阶段为判断道岔归属,目标是基于进路判断法及道岔坐标设计初分、调整、检验等计算步骤判断道岔归属并生成道岔组。以某个布置复杂的技术站咽喉为例,对本文所提出方法进行检验,结果表明该方法能够快速准确地实现咽喉道岔自动分组,有利于铁路数字化设计和智能化生产管理。ed the problem of turnout grouping in the throat area as the problem of the attribution of points in a directed graph to build the station throat model and turnout automatic grouping model based on the directed graph,and propose a two-stage method to solve these two models.The first stage is to identify the parallel routes,with the goal of identifying and generating a complete set of parallel route pairs by using the Depth First Search Algorithm based on the directed throat graph.The second stage is to determine the ownership of turnouts,with the goal of determining the ownership of turnouts and further generating turnout groups based on the route determination method and the coordinate design of turnouts which includes the calculation steps of the initial division,adjustment and inspection.Based on the example of the throat of a complex railway technical station,the proposed method in this paper was tested.The result shows that the proposed method is able to realize automatic grouping of the turnouts in the railway station throat area effectively and accurately,which will be beneficial for the digital design and intelligent operation management of railways.
