高速铁路枢纽站高峰时段通过能力仿真研究

Simulation Research on the Passing Capacity of High-speed Railway Terminal During Peak Hours

高速铁路车站通过能力是高速铁路线路及线网通过能力的瓶颈,其中最为重要的即为枢纽站高峰时段通过能力。本文基于高速铁路车站作业流程,利用目前常用的通过能力计算方法,考虑车站设备状态和各类列车作业流程时间等约束,构建高速铁路车站最大通过能力计算模型,通过事件调度法进行仿真求解。以成都东城际场为例验证模型的可行性,在偏向实际情况及随机状况下分别计算了其高峰时段通过能力,得到了两种情况下车辆设备、列车流相关统计指标,并结合统计指标利用利用率法求得两种情况车站通过能力,对计算通过能力提供了新方法。

The capacity of high-speed railway stations is the bottleneck of the capacity of high-speed railway lines and line networks,the most important of which is the capacity of hub stations during peak hours.Based on the operation process of high-speed railway stations,this paper uses the currently commonly used calculation method of passing capacity,considering the constraints of station equipment status,various train operation process time,etc.,to construct a calculation model of maximum passing capacity of high-speed railway stations,and solves it through simulation by event scheduling method.Taking the Chengdu East Intercity Depot as an example to verify the feasibility of the model,the passing capacity of the peak hours was calculated under the biased actual situation and the random situation,and the statistical indicators related to vehicle equipment and train flow were obtained in the two cases,and combined with the statistical indicators Using the utilization rate method to obtain the passing capacity of the station in the two cases,the research results provide a new method for calculating the passing capacity.
