摘　　要：在南水北调PCCP工程施工中,为了防止预应力钢丝和钢筒发生腐蚀,采用了牺牲阳极法阴极保护技术;文中介绍了南水北调PCCP阴极保护中所采用的阴极保护准则、阴极保护方案、阴极保护检测技术及施工过程中的注意事项,为PCCP管道阴极保护技术的推广提供了参考。During the construction of the PCCP Project of Mid-route of the South-to-North Water Transfer Project, the sacrificial anode protection technology of cathodic protection method is applied to the construction of the PCCP Project, so as to prevent corrosion of both the pre-stressed steel wire and steel cylinder of PCCP. The criteria, scheme, inspection of the cathodic protection method and the relevant attentions during the construction concerned are introduced herein in order to provide reference for popularize the cathodic protection technology for the construction of PCCP pipeline.
