摘　　要：本文利用等效代换的方法建立计算瞬变电磁响应的概念及方法,通过视电阻率和视深度的计算,进行实测剖面的二维电阻率成像,并利用该成像技术探测某水库岩体集中渗漏通道,获得良好的效果。The article establishes the concept and calculation method of transient electro-magnetic response by using equivalent substitution method. Based on the calculation of apparent resistivity and apparent depth the two-dimensional resistivity imaging formation for real observed section is completed. This imaging formation technique is utilized in detecting rock mass concentrated seepage passage of certain reservoir and a good result is achieved.
