摘要
文中对地势起伏段管道进行了非接触磁记忆检测及开挖验证,该技术对管体变形引起的应力集中具有较高检测灵敏度,可作为内检测和外检测的互补技术,加强特殊区域埋地管道的完整性管理。
Non-contact magnetic memory detection and excavation verification were carried out for the pipeline in terrain fluctuation.The technique has high detection sensitivity for stress concentration caused by tube deformation,which can be used as a complement for internal and external detection and can strengthen the integrity management of buried pipelines in special areas.
