摘要
轨枕在有砟轨道结构中起着承力和传力的关键性作用,高速铁路桥上有砟轨道应选用合理的轨枕形式。结合有砟轨道轨枕的应用情况、技术特性、经济性、养护维修等多方面指标,对Ⅲ型轨枕、弹性轨枕、宽轨枕、梯子式轨枕、框架式轨枕、德国B系列轨枕及法国双块式轨枕等7种主要轨枕形式的国内外研究和应用现状进行介绍,并对各种轨枕形式的优缺点进行深入的分析和比较,供高速铁路桥上有砟轨道轨枕结构选型参考。
Ballast track sleepers play the key role of force bearing and force transmission,so the ballast tracks on bridges of high-speed railways should select reasonable sleeper patterns.Considering various indexes of ballast track sleepers such as application situation,technical characteristics,economical efficiency and maintenance,the paper introduces the present research and application situation of main sleeper patterns including type Ⅲ sleeper,elastic sleeper,wide sleeper,ladder sleeper,framework sleeper,B series sleeper of Germany and double-block sleeper of France,and the advantageous and disadvantageous of each sleeper pattern are analyzed and compared deeply.This could be taken for reference for the selection of ballast track sleeper structures on bridges of high-speed railways.
