摘　　要：强制电流阴极保护技术是防止和缓解金属腐蚀的有效措施,因此得到了广泛应用。实现强制电流阴极保护需要辅助阳极的配合,所以应对辅助阳极给予足够重视,但在实际应用和日常维修、维护中,人们更多关注的是阴极保护设备,而对辅助阳极维护较少,重视不够。文章在分析阳极接地电阻对强制电流阴极保护影响的基础上,提出了解决方法。Impressed current cathodic protection technique is a kind of efficient measures for avoiding and slower the metal corrosion, so it was used more and m ore widely. Implementing Impressed current cathodic protection technique need co operating with assistant anode, so assistant anode must be paid attention to. Ho wever, during practical application and routine maintenance, we always put more attention on cathodic protection equipments than assistant anode. Based on influ ences caused by anode grounding resistance for cathode protection, we put forwar d some countermeasures.
