摘　　要：介绍了非接触式磁力扫描技术的原理,采用非接触式磁力扫描技术对长输管道进行了检测应用并进行了开挖验证,检测结果表明,非接触式磁力扫描技术可以在非开挖条件下对管道本体上的缺陷进行有效检测。该技术可在一定程度上弥补内检测的不足,可以作为管道内检测的重要补充手段。The principle of non-contact magnetic scanning technique is introduced and the long-distance pipeline is technically applied and verified by excavation with non-contact magnetic scanning technique. According to the testing result, it shows that the non-contact magnetic scanning technique can ef- fectively test the defects in pipeline under the condition of non-excavation. This technique could make for the deficiencies in internal inspection to a certain extent and can be used as the important supplement measure for internal inspection of the pipeline.
