摘　　要：针对高速铁路高架桥区段贯通地线和信号电缆同沟敷设问题,采用计及接地电阻的贯通地线分段处理方法,结合现有模型建立全并联AT牵引网10导体传输线模型。分析了全并联AT牵引网正常以及TR短路故障情况下贯通地线电位和电流分布情况,对研究贯通地线与同沟敷设的信号电缆之间产生的电磁耦合影响具有一定的参考价值。With regards to problems of laying of through earthing wires and signal cables on the same trench at viaduct section of high speed railway, a sectionalized method based on through earthing wires with consideration of earthing resistance is adopted, with combination of existed models, a full parallel AT traction network 10 conductor transmission line model is established. The paper analyzes the potential and current distribution of through earthing wire under normal operation of AT traction network and under fault condition of TR short circuit, providing certain references for researches of electromagnetic interferences generated from through earthing wires and signal cables laid in the same trench.
