大型客运站股道运用均衡性研究

Research on the Balance of Track Allocation at the Large-sized Railway Passenger Stations

结合客运专线的作业特点和流程、到发线相关作业及运用原则、进路占用原则,分析影响股道均衡分配的主要因素。根据影响股道均衡性分配的因素,建立包含两个目标的股道分配均衡性模型。构建启发式算法并对模型进行求解,证明该算法对求解股道分配均衡性模型的可行性。对某衔接的三个方向双线通过式中间站进行实例计算,并对算例结果进行分析评价,证明该模型的可行性和有效性。

Combine the characteristics and process of passenger dedicated line operation, the related operation and application principles of arrival-departure track and the principle of route occupied. Analyze the main factors which influence the proportionality of track distribution. According to the factors which influence the proportionality of the track distribution, it proves the feasibility of this algorithm which used to solve the model of track distribution. Construct a heuristic algorithm to solve the model, which is solving the possibility of the equilibrium model that aim at track distribution. Take numerical example of two-double-track intermediate station which connects to three directions, and put forward the evaluation indexes of proportionality.
