Study on Advanced Detection by Resistivity Method in Roadway Excavation
Abstract：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.
