摘　　要：由于管道建设历史久远,部分管道存在资料缺失,导致绝缘接头的埋设位置难以确定;本文利用金属磁记忆检测方法,通过检测埋地管道上方地表磁记忆信号变化特征,在不开挖的情况下快速确定了绝缘接头的埋设位置。Due to the long history of pipeline construction and the construction data missing,it is difficult to find out the location of insulation joints;This article uses the metal magnetic memory detection method to detect changes in magnetic memory signals on the surface above buried pipelines,and successfully determines the position of insulation joints.

关 键 词：金属磁记忆 绝缘接头 埋地管道
