铁路车站咽喉通过能力分析研究
|
摘要
为提高铁路车站咽喉区及整个车站的通过能力,运用咽喉区道岔分组简化咽喉道岔及进路优化方法对铁路车站咽喉通过能力进行研究。以进路为研究对象、咽喉通过能力为目标,运用道岔分组原则对咽喉区道岔进行分组,使用坐标计算法和平行进路法分别验证道岔分组的正确性及可行性,并对最大平行进路优化法和最大概率进路优化法在进路分配方案中的运用进行对比。最后以某中间站为例,在综合考虑接发车的优先等级和调车作业干扰的情况下,优化接发车进路,以提高车站到发线、咽喉区及整个车站的通过能力。结果表明,运用进路优化方法在一定程度上能够很好地指导现场作业,提高车站的作业效率。
To improve the throughput capacity of the railway station's throat area and the entire station, this paper studies the through capacity of the station throat area by grouping the turnouts and optimizing the access routes. The turnouts in the throat area are grouped and then its accuracy and feasibility are verified with coordinate calculation method and parallel routing method. The application of the maximum parallel route optimization method and the maximum probability route optimization method in the approach distribution plan are compared. Taking an intermediate station as an example, in consideration of the priority of the receiving/departing train and the interruption of the shunting operations, the access route of the receiving/departing train is optimized, and the through capacity of the station to the dispatch line, the throat area, and the entire station are improved. The results show that the use of route optimization methods can guide the optimization of on-site operations to a certain extent and improve the operation efficiency of the station.
