摘　　要：对交流电力牵引区段轨道电路中普遍存在的各种信号迂回回路进行分析,计算迂回回路的长度,研究断轨灵敏度系数与迂回电路长度的关系,提出电化区段轨道电路如何避免牵引回流对轨道电路影响的解决措施。Various signal bypass loop generally existing in track circuit within electrification districts were analyzed. Based on the calculation of the length of the bypass loop, the relationship of the sensitivity co-efficient of broken rail and the length of bypass loop circuit were studied. In the end, the author proposed a solution to avoid the influence of tract return current to the track circuit within electrification district.
