摘　　要：本文通过对管道站场埋地管道电偶腐蚀实例和接地体材料的电位分析，指出了站场管道电偶腐蚀的原因、特征及对站场安全的威胁，并提出了技术改进措施和建议。The galvanic corrosion examples of the buried pipeline in the stations and the potential of the ground materials are analyzed. The cause and the characteristics of the galvanic corrosion of the bur ied pipeline in the station as well as their threat on the safety of the station are discussed. The technological improvement measures are proposed.
