Experimental Studies on the Changes in Resistivity and Its Anisotropy Using Electrical Resistivity Tomography
Figure 7
The diagram of apparent resistivity sets corresponding to effective depths. Because the effective depth of Wenner- array was evaluated to be about 0.5 time of electrode spacing [36, 37], the 12 apparent resistivity sets were corresponding to the effective depths of about 1.5 mm, 4.5 mm, 7.5 mm, 10.5 mm, 13.5 mm, 16.5 mm, 19.5 mm, 22.5 mm, 25.5 mm, 28.5 mm, 31.5 mm, and 34.5 mm for sample YN1, and 6 ones were corresponding to the effective depths of about 2.5 mm, 7.5 mm, 12.5 mm, 17.5 mm, 22.5 mm, and 27.5 mm for sample YN2 according to Figure 6.
