广州南站到发线通过能力查定研究

我国高速铁路车站运输能力查定等基础理论研究滞后于高速铁路运营实践,通过对高速铁路车站到发线通过能力查定开展理论计算方法的研究,修正高速铁路运能查定利用率计算参数。以旅客发送量最大的广州南站为研究对象,运用分散自律调度集中CTC设备精准采集京广场和广珠场办理的终到入库列车、库出始发列车、中转列车、立折列车等4类列车占用到发线时间,分析查定广州南站到发线通过能力,得到广州南站到发线通过能力存在潜能、广州南站通过能力受限于咽喉通过能力的研究结论,为运能日益紧张的广州南站扩能改造提供理论参考。

A Research on Passing Capacity Checking of Guangzhou South Railway Station Arrival-departure Track

The basic theoretical research of transportation capacity checking of high-speed railway station in China lags behind the operation practice of high speed-railway. In this paper, we carry out theoretical calculation methods to study the arrival and departure track passing capacity of high-speed railway station, revises the calculation parameter of transportation capacity checking utilization of high-speed railway station. Taking Guangzhou South Railway Station, the largest passenger volume of high-speed railway station in China as a study case, we use Decentralized and Autonomous CTC equipment to collect the time of occupy arrival and departure track of four sort of train conducted by Beijing-Guangzhou yard and Guangzhou-Zhuhai yard accurately, such as receiving to depot train, originating from depot train, transference train and immediate return train, check and analyze the arrival and departure track passing capacity of Guangzhou South Railway Station, point out that there is potential in the arrival and departure track passing capacity of Guangzhou South Railway Station, and make it clear that the transportation capacity of Guangzhou South railway station is constrained by throat passing capacity. This research work would provide theoretical references for the capacity expansion and transformation of Guangzhou South Railway Station which transportation capacity is becoming increasingly tense.
