摘　　要：三峡船闸钢闸门防腐是制约船闸检修工期的主要因素。钢闸门腐蚀的主要原因是电化学腐蚀。分析阴极保护技术和涂层防腐技术的机理和优缺点,认为三峡船闸钢闸门防腐既治标又治本的最佳方法是阴极保护技术和涂层保护结合使用。The anti-corrosion of the steel gate of Three Gorges dam navigation lock is the major factor that impacts the time spent on the check and maintenance of navigation lock. The corrosion of the steel gate is mainly electro-chemical corrosion. This paper analyzes the mechanism and the advantages ＆ disadvantages of cathodic protection and coating anti-corrosion techniques, and comes to the conclusion that the best anti-corrosion method, which answers to all demands, is the combination of both cathodic protection technique and coating technique.
