  中文摘要

  随着高速铁路的大年夜范围建立、既有线提速改革及重载铁路的快速开展,作为铁路主要基础装备的轨道结构需求不时更新、技巧不时完美。高速铁路的技巧中间是高速度,它对轨道结构就有了高平顺性和高动摇性的请求。传统的轨道结构已不适应今朝铁路开展的需求,结构方法和设计方法必须响应修改。

  在高速开展的明天,轨道交通曾经成了主流的交通对象,特别是城市轨道交通,而轨道交通现在基本都采取无砟轨道的技巧停止施工,它比拟于有砟轨道确实有必然的优势但也不成防止有各方面的优势。

  随着我国铁路建立水平的不时开展和提高,铁路的建立形式正逐渐从客货共线方法向客货分别方法改变,经过对客运专线无砟轨道与有砟轨道的技巧、经济比拟,无砟轨道已成为客运专线的开展趋势。因为国际铁路建立和运输条件与国外存在差异,没有一种成熟的结构方法可以完整用“拿来主义”坐在国际应用。因此我国铁路轨道技巧的开展应当总结国外铁路无砟轨道与有砟轨道的结构特色,充沛剖析国际的铁路结构和应用条件,选择技巧先辈、经济公道的轨道结构方法,对比剖析无砟轨道与有砟轨道的各类技巧,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 cons
