摘要
一种无损高分辨率电磁探测技术 (TEM) -瞬变电磁法 ,它不同于探地雷达。它应用探测的电导率数据成图 ,可提供解释出地下埋藏的金属物体及相关信息。主要用于地下环境工程、市政工程、考古、军械遗弃场地的普查探测等领域。在设计、开挖、施工过程中 ,能够充分了解地下金属物体 (金属管线等 )的分布及地质情况。也能充分利用探测成果在盲区做集中、具体的工作。由高分辨率瞬变电磁技术所得的信息是非常重要的。
The transient electromagnetic exploration method is a new high resolution measurement technique in the present geophysical exploration field It is different form GPR Mapping with the measured electroconductivity data Interpretation the electroconductivity data, locate the underground metal and get more information Application on environment engineering, city engineering, archaeology, unexploded ordnance to exploration More underground metal(pipe line)and construction information is taken to design and dig Use the exploration result to go on the next detail task safety It is very important to use the information acquired from high resolution transient electromagnetic exploration method
