摘　　要：通过对含前方异常体、含后方异常体、含前方和后方异常体3种模型的三维电法数值模拟表明,视电阻率极值位置与异常体位置之间存在较大差异,相比于后方异常体前方异常体异常幅度小,通过2种不同的成图方式可以区分前方异常体和后方异常体。实例分析表明,电阻率法超前探测与其它超前探测方法相结合能够达到准确探测前方异常体的目的。By three - dimensional electrical method numerical modeling of three models （ the anomalous body in the front, the anoma- lous body in the back, the anomalous body in the front and the rear）, this paper shows that there is a large deviation between the posi- tion of the apparent resistivity extreme value and the position of the anomalous body. Compared to the abnormal body in the rear, anom- aly amplitude of the anomalous body in the front is small. The anomalous body can be identified by two different mapping methods. Ap- plication examples show that resistivity method can explore the anomalous body accurately combined with other advance detection meth- ods.
