摘要:
强电线路与埋地管道共用一个走廊时，会对管道造成交流干扰腐蚀。针对管道受交流干扰影响，传统的电参数测量不适于确定交流干扰参数，也不适于评估交流干扰影响的程度。介绍了管道
交流干扰参数的测试方法，包括实验室的电化学测量和腐蚀率估算方法，以及管地电位、交流电流密度和电流密度比的现场测量方法，重点分析了当前作为交流干扰腐蚀重要指标的电流密度测量方
法，详细阐述了用于现场测量交流干扰参数的试片的设计和安装方法。进行交流干扰腐蚀评价必需的两个参数值：交流电流密度、交流电流密度与直流电流密度之比，不能在管道上直接测量得到，因此推荐采用试片法进行电参数和电化学参数的测量。
Abstract:

Power transmission line could cause AC interference corrosion of the buried pipeline when it shares a corridor with the pipeline. Because the measurement methods of traditional electric parameters are not suitable for measuring the AC interference parameters of pipeline suffered from AC interference，they can not be used to evaluate the level of AC interference. In this paper，the test methods of AC interference parameters，including the method of electrochemical measurement and corrosion rate estimation in laboratory，and field measurement method of pipe-soil potential，AC current density，the ratio of AC/DC current density，are introduced. As an important indicator of AC interference，the measurement method of current density is especially addressed. The design and installation method of coupon used to measure the AC interference parameters in field are illustrated in detail. The two indispensable parameters（AC current density，the ratio of AC/DC current density）for the evaluation of AC interference corrosion can not be directly measured from the pipeline，the measurement methods of electric and electrochemical parameters with specimens are recommended.
