摘要
基于城市地下目标物探测,该文提出了小回线瞬变电磁法探测技术,研究并开发了拖拽式瞬变电磁仪跨环削偶线圈及观测模式,采用烟圈成像对资料进行快速解译。最后通过城市地下管线及建筑桩基探测实例,说明点测模式及连测模式下的小回线瞬变电磁法,可以快速高效地进行城市地下目标物探测,具有良好的应用前景。
Based on the detection of urban underground targets,this paper puts forward the detection technology of small loop transient electromagnetic method,studies and develops the cross ring paring couple coil and observation mode of towed transient electromagnetic instrument,and uses the smoke circle imaging to interpret the data quickly.Finally,through the detection examples of urban underground pipelines and building pile foundations,it shows that the small loop transient electromagnetic method under point measurement mode and continuous measurement mode can detect the urban underground targets quickly and efficiently,and it has a good application prospect.
