武广高速铁路长沙南站通过能力影响因素分析

An Analysis on the Factors Influencing Carrying Capacity of Changshanan Railway Station of Wuhan-Guangzhou High-Speed Railway

随着国家高速铁路建设的推进,武广高速铁路衔接通达的线路不断增加,行车量也逐步增加。长沙南站和衡阳东站作为多方向接入车站,分别与沪昆高速铁路和湘桂铁路交汇,长沙—衡阳区段行车量达到143.5对/d,运输能力难以满足日益增长的旅客运输需求。在阐述武广高速铁路长沙南站列车开行情况的基础上,分析研究车站间隔时间、列车开行方案、设备设施布局、到发线运用等影响长沙南站通过能力的主要因素,提出采用分段解锁方式、调整列车开行方案、改造完善车站设施、优化到发线运用等措施,为进一步提高长沙南站的通过能力提供借鉴。

With the development of high-speed railway in China, the number of links and traffic of Wuhan-Guangzhou high-speed railway is increasing. Changshanan Station and Hengyangdong Station, as multi-direction access stations, meet with Shanghai-Kunming high-speed railway and Xiang-Gui railway respectively, and the traffic volume in the Changsha-Hengyang section is 143.5 pairs per day, which means the transportation capacity is difficult to meet the increasing demand for passenger demand. By elaborating the train operation situation of the Changshanan Station in Wuhan-Guangzhou high-speed railway, the main factors affecting the capacity of Changshanan Station including station interval time, train operation plan, equipment layout, and operation of the arrival and departure line are analyzed. In order to improve the capacity of Changshanan Station, this paper puts forward the measures such as adopting the method of section unlocking, adjusting the train operation scheme, improving the station facilities and optimizing the operation of the departure line.
