高速铁路轨道技术综述

研究目的:高速铁路的轨道必然比普通线路具有更高的安全性、可靠性和平顺性,为保证轨道结构的这些要求,轨道各部件的力学性能、使用性能和组成为结构的整体性能都比普通轨道部件高得多。本文旨在提供长期以来国内外在高速铁路轨道方面的研究成果与应用经验,以期满足中国高速铁路建设和发展的需要。研究结论:对各国在高速铁路轨道结构、客运专线和高速铁路对轨道结构的要求、钢轨、轨下基础、扣件、道床等方面的技术指标做出分析和评述,并对一些关键技术的发展提出了思路。

Overall Comments on Track Technology of High-speed Railway

Research purposes: The track of high-speed railway requires higher safety,reliability and regularity than that of ordinary railway,so there are much higher requirements of mechanics property,applicable property and integral property of structure for the all components of track than that of ordinary track in order to satisfy the requirements(mentioned) above of track structure.The purposes of this paper are to provide research achievements and applied(experiences) regarding to the track of high-speed railway at home and abroad so as to satisfy the needs of construction and(development) of high-speed railway in China. Research conclusions:The analysis and comments are made on the requirements and the technical indexes of rail,(sub-rail) foundation,fittings and ballast bed for track structure of passenger dedicated railway line and high-speed railway in many countries,and the thinking is offered for development of the key track technologies.
