摘要
简要介绍大铁路和地铁系统轨枕的类型,通过分析机车的授流和回流,确定并行区段采用接触轨作为授流方式。详细分析了接触轨绝缘底座各种安装方式的优劣,提出绝缘底座优先采用加长轨枕合架的安装方式。在对大铁路机车和地铁机车的基本限界进行分析后,首次提出在大铁路与地铁并行区段接触轨与走行轨的相对尺寸参数;并结合相关工程案例,介绍了加长轨枕的特殊设计。
The sleeper forms of subway system and railway system were introd.uced in this paper, by analyzing the current collection mode and return system of locomotives, the contact rail was chosen in the parallel section. In a detailed analysis of the characteristics of various installation modes of the contact rail insulation support, the insulation supporting preferred to be installed with lengthened sleeper. By analyzing the basic clearance for railway locomotives and subway locomotives, the relative size parameters of the contact rail and the running track in the parallel section of subway system and railway sys- tem were first presented, and the special design for longer sleepers was proposed combined with the related projects.
