高速铁路夕发朝至列车开行模式综合比选

Comprehensive Comparison and Selection of Operation Modes of Sunset-departure and Sunrise-arrival Train on High-speed Railway

根据目前采用的高速铁路综合维修天窗开设形式,提出等线、下线、下线-上线共3种夕发朝至列车开行模式.构建备选方案生成模型、对模型求解流程进行分析,并提出开行模式比选指标及规则.以我国天津-长沙和北京-广州高速铁路夕发朝至列车OD进行实例分析.结果表明,基于我国铁路实际,中长距离列车OD首选下线开行模式,对于长距离列车OD,首选等线开行模式,但具体下线和等线地点需根据线路布置情况科学选择.下线-上线开行模式的速度优势需要在一定条件下才能体现.

The organization modes of sunset-departure and sunrise-arrival train, for example, waiting for integrated maintain time（IMT） on a high speed railway（HSR） station（WHRS）, transfer from HSR to conventional railway（CR） before IMT and arriving at the destination（THCD） on CR, transfer from HSR to CR before IMT and from CR to HSR after IMT（HCCH）, were proposed according to the present adopted shape of the IMT on HSR. Alternative scheme generation model was built, solving process of model was analyzed,and rule and index of comparison and selection of operation mode was put forward. The sunset-departure and sunrise-arrival train OD Tianjin-Changsha, Changsha-Tianjin, Beijing-Guangzhou and Guangzhou-Beijing were used to solve the model and compare and choose the schemes. The result shows THCD is the first choice for the medium or long distance train OD. WHRS is preference for the long distance train OD. But the city transfer from HSR to CR and waiting for IMT should be selected scientifically according to the factual data of HSR or CR. The faster travel velocity of HCCH is achieved in certain conditions.
