| 摘 要： | 由于无砟轨道板中纵横交错的钢筋网络与钢轨产生电磁耦合导致无绝缘轨道电路传输长度大大缩短.本文根据无绝缘轨道电路对无砟轨道适应性的电磁分析,定量计算出无砟轨道对无绝缘轨道电路影响的大小.通过建立一种新的轨道电路模型及仿真来验证钢轨等效阻抗计算的正确性.

| Abstract: | Because of electromagnetic coupling between steel bar networks in ballast-less track plate and track,the transmitting length of jointless track circuit is shortened greatly.Based on the electromagnetic analysis of the adaptability of track circuit to ballast-less track,this paper assesses the influence of the ration on uninsulated track circuit caused by circuit ballast-less track.A new model of track circuit and its simulation are used to confirm the correctness of calculation of the equivalent impedance. |
