摘　　要：南水北调中线工程北京段PCCP输水管采用外防腐涂层与阴极保护技术相结合的防腐措施,属国内首例。本文阐述了长距离、超大口径PCCP输水管实施阴极保护的必要性、方案选择及设计、保护准则、工程布置等,为同类输水工程提供借鉴,并为编制国内PCCP管阴极保护技术标准提供依据。As the first national case, surface coating and cathode protection are applied together for corrosion protection of PCCP in the part of Beijing of South-to-North Water Diversion Middle Route Project. The necessity, scheme comparison and design, protection criteria, and engineering arrangement of cathode protection for long-distance big diameter PCCP are introduced in this paper. These might provide some references for other similar projects and a basis for formulating the technical standards.
