摘　　要：在调查分析埋地供水管道腐蚀状况及腐蚀原因的基础上,通过实验室实验和现场测试,分析了埋地供水管道外部腐蚀结构成分,证明了电化学腐蚀和微生物腐蚀是引起埋地供水管道腐蚀的主要原因。On the basis of investigating the current corrosion situation and corrosion causes of buried metallic pipe in water distri- bution, by taking experimences in lab and testing in field, the structural components of metallic pipe exterior corrosion were analyzed . It was proved that the electrochemical corrosion and microbiologically influenced corrosion are the main reasons of pipe corrosion in water distribution.
