通过分析鱼龙岭接地极入地电流对西气东输二线埋地钢质管道的影响，预测管道防腐层发生阴极剥离及管体产生重大腐蚀的可能性较低，管道阴极保护电位偏移较大，导致阴极保护电源设备运行异常。由此，需对西气东输二线管道采取适当的杂散电流干扰缓解措施。
By analyzing the effect of stray current that originates from Yulonglin ground electrode to the underground pipeline of West East Gas Pipeline 2,it’s less likely to have underground pipeline coating’s disbonding or pipe wall’s serious corrosion.However,the shift of cathodic protection potential causing from the effect may lead to abnormal cathodic protection power supply operation.As a result,it’s necessary to take appropriate mitigation measures to West East Gas Pipeline 2.
