广州南站咽喉通过能力查定研究

高速铁路运输组织与普速铁路有根本性差异,我国铁路企业查定高速铁路车站咽喉通过能力仍然沿袭普速铁路区段站通过能力计算方法。通过对高铁站咽喉通过能力查定进行研究和建模,以全国旅客发送量最大的高速铁路车站广州南站为研究标本,对现行普速铁路车站通过能力利用率计算方法进行修正。同时运用分散自律调度集中CTC设备精准采集广州南站接发列车占用咽喉时间数据,实际查定和分析广州南站分车场分咽喉分方向的咽喉通过能力,并提出相关提高高速铁路车站咽喉通过能力措施,对我国高速铁路车站运输生产、站场设计和扩能改造提供参考。

A Study on Throat Area Through Capacity Checking of Guangzhou South Railway Station

There is a fundamental difference between the high-speed railway transportation organization and that of the conventional speed train. The railway enterprises in China check the throat passing capacity according to calculation method of the normal speed train. This paper studies and models the throat passing capacity checking of high-speed railway station, and amends the calculation method of utilization of the throat passing capacity checking of the normal speed train station. Taking Guangzhou South Railway Station, the largest passenger volume of high-speed railway station in China as the study case, we accurately collect throatoccupying time data of Guangzhou South Railway Station receiving and departing trains by means of Decentralized as well as Autonomous CTC equipment. The paper examines and analyzes the throat passing capacity of Guangzhou South Railway Station from aspects of yard, throat and direction, and puts forward the relevant improvement measures of throat passing capacity of highspeed railway station, which can provide reference for transportation production, station design and capacity expansion of high-speed railway stations in China.
