摘　　要：综述了交流干扰相关参数(如交流干扰电压、交流电流密度以及管道阴保电位)有效测试技术及交流干扰风险评价方法的最新研究成果,指出了目前交流干扰相关参数测试过程中存在的误区和交流干扰风险评价过程中应注意的问题,以期提高对交流干扰参数测试和交流干扰风险评价的认识,最后展望了该领域的发展趋势。The matter of AC interference with buried pipelines from overhead power lines or AC electric traction systems has attracted much attention in recent decades. However, the testing technologies and risk assessment methods have not been well-understood. In this work, the latest acquisition on effective measurements of AC interference parameters, such as AC voltage, AC current density and real polarization potential of the interfered-pipelines, was reviewed. Also, AC risk assessment methods were summarized. After that, current problems in AC parameters measurements and AC risk assessment were discussed. Finally, several comprehensive suggestions were proposed for the future research.
