基于地磁原理的非金属地下管线探测技术的研究与应用

地下非金属管线的探测是一项世界性难题，无论是地下管线探测仪还是地质雷达，其探测效果都不太理想。目前，一种利用地球磁场原理探测地下非金属管线的探测方法正在被推广使用。为此，以探地成像仪在昆明市某区域大管径地下非金属给水管线的探测为例，说明探地成像仪的探测成像过程，并得出该区域地下非金属管线的地磁成像特征，可为将来类似地下管线探测提供参考，同时也得出了利用该探测技术能够较好的解决一些埋设年代久远的城市地下管线的探测与识别问题。

Research and Application in the Nonmetal Underground Pipeline Detection Technology Based on the Geomagnetic Principle in Kunming City

Underground pipeline detection of nonmetal is a worldwide challenge,regardless of geological radar detectors or underground pipeline detectors,and its effect is undesirability.At present,a method which based on the principle of geomagnetism detection nonmetal underground pipeline is being used.This paper bases on the under the earth imaging instruments used in a regional exploration prospects into Kunming underground water supply pipeline diameter larger for example,summarizes the regional underground pipel...
