中文摘要
随着高速铁路的大规模建设、既有线提速改造及重载铁路的快速发展，作为铁路重要基础设施的轨道结构需要不断更新、技术不断完善。高速铁路的技术核心是高速度，它对轨道结构就有了高平顺性和高稳定性的要求。传统的轨道结构已不适应目前铁路发展的需要，结构形式和设计方法必须相应改变。
在高速发展的今天，轨道交通已经成为了主流的交通工具，特别是城市轨道交通，而轨道交通现在基本都采用无砟轨道的技术进行施工，它相比于有砟轨道确实有一定的优势但也不可避免有各方面的劣势。
随着我国铁路建设水平的不断发展和提高，铁路的建设模式正逐步从客货共线形式向客货分离形式转变，通过对客运专线无砟轨道与有砟轨道的技术、经济比较，无砟轨道已成为客运专线的发展趋势。由于国内铁路建设和运输条件与国外存在差异，没有一种成熟的结构形式能够完全用“拿来主义”坐在国内运用。因此我国铁路轨道技术的发展应当总结国外铁路无砟轨道与有砟轨道的结构特点，充分分析国内的铁路结构和运用条件，选择技术先进、经济合理的轨道结构形式，对比分析无砟轨道与有砟轨道的各种技术，从而优化轨道结构。

Abstract
With the high speed railway, large-scale construction of existing railway-speed-increasing transformation and overloaded railway of rapid development, as an important railway infrastructure of track structure need to constantly updated, technology improvement. High-speed rail technology core is high speed, it to track structure is the GaoPingShun sex and the high reliability requirements. The traditional rail structure can meet the needs of the development of the current railway, structure form and design method must change accordingly.
In the current rapid development of rail transit has become the mainstream of transportation, especially on urban rail transit, and rail traffic now are the basic technology to track a frantic jumble no construction, it is compared to the frantic jumble of a certain track advantage but also hard to avoid the disadvantages.
With China's level of railway construction development and improve, railway construction mode gradually from the passenger and freight line forms to passenger separation form change, through to the special passenger line frantic jumble no tracks with a frantic jumble of technology, economy comparison orbit, frantic jumble no track has become the development trend of the passenger special line. Because domestic railway construction and transportation conditions and foreign different, not a kind of mature structure form can completely with "copycat" sat in the domestic use. So China's railway track technology development should be summarized foreign railway tracks with a frantic jumble no frantic jumble the structure characteristics of the track, the full analysis of the domestic railway structure and applying condition, select the advanced technology, reasonable economy of track structure form, comparison and analysis of the frantic jumble no tracks with a frantic jumble of orbit technology, so as to optimize the rail structure.
