通过建立试验装置, 模拟现场进行试验, 得出在平行和交叉等不同情况下交流电气化铁路杂散电流对管道的干扰规律。同时, 进行交流电气化铁路杂散电流干扰的理论推导, 得出在交流电气化铁路杂散电流干扰不同的工况条件下, 埋地金属管道的管地电位的计算公式, 并以此为基础编制干扰预测软件, 为如何进行杂散电流的防护及排流提供理论依据。

By setting up test equipment to simulate the actual situation, the interference law of stray current of alternating current (AC) electrified railway on buried pipelines under the condition of parallel and cross was obtained. The formula of pipe-to-soil potential of buried pipelines under different working conditions was obtained by theoretical analysis. Based on it, a forecasting software was edited, which provided theoretical basis for stray current protection.
