老泰铁路连接线主要技术方案研究

Research on the Main Technical Scheme of Proposed Laos-Thailand Railway Connecting Line

研究目的:老泰铁路连接线是打通中老铁路和中泰合作铁路“最后一公里”的关键工程,也是形成泛亚铁路中通道运输能力的关键环节,对促进区域国家合作与发展,造福沿线地区人民具有重要意义。受制于老泰铁路连接线建设进度,泛亚铁路中通道的运输能力尚未形成,也不利于中老铁路整体运输效益的提升。本文对老泰铁路连接线功能定位、客货运量、铁路主要技术标准、通关模式、线路走向、换装方案、新建湄公河特大桥方案、跨境列车列控模式等进行系统研究。研究结论:(1)推荐采用中国铁路标准、准轨系统,单线(预留双线条件);(2)推荐采用两地两检通关模式、两侧均设换装站;(3)于既有桥下游约30 m新建湄公河特大桥,桥墩对孔布置,为三线桥;(4)跨境旅客列车在本线区间CTCS-2和CTCS-0列控模式自动切换;跨境货运列车在本线运行维持中老铁路机车信号与列车运行监控装置结合模式不变;(5)本研究成果对跨境铁路建设具有参考价值。

Research purposes: The proposed Laos-Thailand Railway Connecting Line is the key project of "the last kilometer" to connect the China-Laos Railway and China-Thailand Cooperation Railway and the key link to form the transportation capacity of the middle passage of the Trans-Asian Railway, and it is of great significance to promote the cooperation and development of regional countries and benefit the people in the surrounding areas. However, subject to the construction progress of Laos-Thailand Railway Connecting Line, the transportation capacity of the middle channel of the Trans-Asian Railway has not yet been formed, which has also been unfavorable to the transportation benefit of the China-Laos Railway. This paper makes a systematic study on the function positioning, passenger and freight volume, main railway technical standards, customs clearance mode, alignment, transshipment scheme, new Mekong River Railway Bridge scheme, the operation control model of cross-border trains, etc.Research conclusions:(1) It is recommended to adopt Chinese Standard gauge railway system, and the number of main lines shall be single track with reserving double tracks.(2) It is suggested that the "border control in separate locations" customs clearance mode and "transshipment in both sides" are adopted.(3) It is suggested that a new Mekong River Bridge is set at about 30 m downstream far from the existing bridge, and the piers of the new bridge are aligned with the existing piers, and the scales of new bridge are three tracks, which are single-track for meter gauge railway and double-tracks for standard gauge railway.(4) The cross-border operation of passenger trains automatically switches between CTCS-2 and CTCS-0 in the section, and the cross-border freight train maintains the combination mode of locomotive signal and train operation monitoring device as same as China-Laos Railway.(5) The research results have reference value for the construction of newly-built cross-border railway.
