摘　　要：针对已往轨道电路参数测量方法均需要停止轨道电路工作的弊端,以UM71无绝缘轨道电路为例,提出了一种方便、简捷的道碴电阻测量方法,即查表测试法,编制了道碴电阻测试表。为了方便查表法的应用,设计了道碴电阻测试查询软件。In allusion to the disadvantage of the methods for measuring the parameters of track circuit, in which the operation of track circuit must be halted, the paper takes the example of UM71 jointless track circuit and puts forward a convenient method for measuring the ballast resistance, i.e. the querying method. A querying software is designed for the convenient utilisation of querying method.

关 键 词：轨道电路参数测量 无绝缘轨道电路 道碴电阻 钢轨阻抗
