摘　　要：对朔黄线UM71无绝缘、多信息轨道电路道床漏泄及红光带状况进行实地采样比对测试,对雨雪天气轨道电路道床电阻进行仿真计算,对测试和计算结果进行分析,并有针对性地研究生产具有绝缘性能的金属轨距档板、在轨距档板处加装L型复合材料绝缘板,提高钢轨与轨枕的绝缘性能,对漏泄严重区段进行限入电压普调,增强轨道电路在雨雪天气的运行能力等整治方案,值得借鉴。The paper compares the tests of red-light strip states of UM71 multi-information jointless track circuit ballast of Shuo-Huang line by field sampling,the ballast resistance in rain and snow weather is simulated and calculated with the analysis of the tests and calculation results.It studies to produce metal gauge plate and installing L-type insulating board in the gauge plate to improve the insulation performance of rails and sleepers.For serious ballast resistance sections,it puts forward to adjust limited voltage,in order to enhance operating capacity of track circuits in rail and snow weathers.
