摘　　要：对目前常用的埋地管道阴极保护电位测量方法和适用场合进行了对比分析。在此基础上,详细介绍了密间隔电位测量(CIPS)方法和极化探头法及其应用,总结了几种专门用于消除IR降的电位测量技术。最后,提出了特殊环境和特殊位置处的管段阴极保护电位测量中需注意的问题。Several conventional measurement methods for cathodic protection potential of buried pipelines are introduced and compared. The close interval potential survey （CIPS） method and the polarized probe method are introduced in detail and several potential measurement techniques which are designed to eliminate the IR drop are summarized. Some noticeable problems about cathodic protection potential measurements of special pipeline section are put forward and discussed.
