发电厂煤码头钢桩阴极保护──辅助阳极系统论证

Cathodic Protection of Steel Piles of Coal Pier Head in Power Plant ——A Verification of Auxiliary Anode System

根据阴极保护原理，论证了在长江口咸淡水交替的环境介质中，码头钢桩宜采用外加电流阴极保护。实桩试验表明，用高硅铸铁作为辅助阳极材料，采用侧壁式安装方法固定阳极，是行之有效的。

On the basis of the principle of cathodic protection, the verification shows that an impressed current cathodic protection is suitable for steel piles in the environment and the actual pier tests indicate that the protection method is effective. A high silicon cast iron is used as an auxiliary anode and sidewall installation for fixing anodes.
