摘　　要：介绍朔黄铁路25 Hz轨道电路分路不良潜在的危险性,对产生原因进行分析。并有针对性地通过调整技术参数,提升轨道电路灵敏度;采用监控盒方法,提高轨道继电器返还系数;提高轨面电压,击穿氧化膜层;采用"计轴"方案,脱离锈蚀轨面;轨面高温喷涂,解决严重锈蚀等措施,取得良好整治效果,值得借鉴。This paper introduces the potential dangerous duo to bad shunting of 25 Hz track circuits in ShuoHuang railway with the analysis of the causes, and puts forward the measures such as adjusting technical parameters to enhance the sensitivity of track circuit, adopting the monitoring box method to improve the track relay return coefficient, improving the track surface voltage to break oxidation film, adopting the ＂axle-counting＂ scheme to get clear of rusted rail surface and carrying out high temperature spraying on rail surface to solve the serious corrosion. The measures have good effect and are useful for reference.
