摘要
讨论了大定源瞬变电磁资料处理的方法,并和基于中心回线原理处理结果进行比较,发现基于中心回线原理处理会在回线边缘造成视电阻率偏大。铁路工程勘察采用瞬变电磁法时,要获得准确的地电信息,必须采用合适的装置及处理方法。
The data processing of large-fixed loop TEM method is discussed,and result is compared with the theory of centre loop. It is found that the processing based on center loop leads to big apparent resistivity. Adopting TEM method in the exploration of railway needs to obtain the exact geoelectric information,uses appropriate device and processing method.
