本文首先针对综合分析法在高速铁路车站通过能力计算上存在的问题,结合CTC系统的接发车原理和自动采点原理,总结出综合分析法的不适应性。其次,深入研究综合分析法中列车占用到发线时间、列车占用咽喉区时间、一昼夜停止作业时间等关键参数的取值问题,将参数取值细致化、标准化,使综合分析法的计算结果更符合现场实际运用的需要。最后,运用综合分析法计算了枢纽车站长沙南站的通过能力。为了使研究内容更具有实际参考意义,计算过程中涉及的数据均来源于现场实际使用的数据形式——LKJ数据表、列车运行图、CTC监控录像等,并给出了具体的计算步骤,可以为以后的优化研究提供参考。

This study focuses on the problems of a comprehensive analysis method in the calculation of carrying capacity of high-speed railway stations. First, combining the centralized traffic control(CTC) system and the automatic reading time principle, the study summarizes the incompatibility of the comprehensive analysis method. Second, the study investigates the value of key parameters in the comprehensive analysis method, such as the time occupied by trains on the arrival and departure track as well as in the station throat, and the stop operation time of a single day and night, thus providing detailed and standard parameter values, which makes the result of the comprehensive analysis more suited for actual needs of the station. Finally, the comprehensive analysis method is used to calculate the passing capacity of Changsha south station. The data involved in the calculation process are derived from actual data formats used in the field, such as the LKJ data table, train diagram, and CTC monitoring video, which ensure that the research finding shave practical significance. The specific calculation steps are described to provide a reference for future research.
