山区重载铁路设计探讨

Discussion on the Design of Heavy-haul Railway in Mountainous Area

重载铁路因运量大、效率高、运输成本低等被国际公认为铁路货运发展的主方向,我国近年来已陆续建设了部分重载铁路,但随着社会经济的发展,还需要不断完善重载铁路建设。文章结合已开通运营的重载铁路现状及山区某重载铁路设计体会,从线路选线、设计速度和限制坡度、站型布置、到发线有效长度确定四个方面对山区重载铁路设计进行探讨,并结合日益突出的国家能源保障问题,明确我国未来发展重载铁路技术的方向和目标。

Heavy-haul railway is internationally recognized as the main development direction of railway freight because of its large capacity, high efficiency and low transportation cost. In recent years, China has successively built some heavy-haul railways, but with the development of society and economy, it is necessary to continuously improve the construction of heavy-haul railways. Based on the current situation of heavy-haul railway in operation and the design experience of a heavy-haul railway in mountainous area, this paper discusses the design of heavy-haul railway in mountainous area from four aspects: route selection, design speed and limited slope, station layout and determination of effective length of arrival and departure lines. Combined with the increasingly prominent national energy security problem, the development direction and goal of heavy-haul railway technology in China in the future are clarified.
