摘　　要：在对层式大地结构情况下强电系统与通信设备之间阻性耦合问题多年研究的基础上,给出了交流电气铁道对地下电缆、金属管线等通信设施地电位的计算方法,并将计算结果与目前通行的三种方法的计算结果进行了比较。结果表明:本文所给出的计算公式更加符合实际。Based upon many-year research works for analyzing the resistive coupling characteristics between power system and telecommunication equipment in stratified soils, a ground potential calculation method is offered on the earthed telecommunication equipment and other underground metal pipes seated near a. c. electric railway. Results obtained by this calculation method compare with those obtained by three other methods usually used shows that the calculation expression offered by this article is more in conformity with actual circumstances.
