摘　　要：文中针对目前地下管线探测的难点问题之一(近间距平行地下管线),首先介绍了直连法、压线法及夹钳法三种方法,接着通过三种模型讨论了管线定位、定深的效果。最后给出结论:直连法与夹钳法是管线探测的首选方法,然后可以考虑倾斜压线法或水平压线法;在管线定深中,70%法测量精度高于直读法。Aiming at one of the difficult problem of underground pipeline detection （ near distance between parallelunderground pipeline）, first, charging method and clamp me t h o d and induction me t h o d were introduced,and thenthrough thethreekinds of model theeffects of thepipelinelocation, depth were discussed. T h e conclusion was giv-en ：charging method and clamp me t h o d were the first choice me t h o d for pipeline detection, and then the tilt line orlevel line method were considered; In the pipeline d e p t h, the m e a s u rement accuracy of 706 w a s higher than the di-rect reading metliod.
