Research Progress on the Influence of AC and DC Stray Current on Soil Resistivity
The influence of AC and DC stray currents on soil resistivity is focused,and the experimental exploration and cognition in this field at home and abroad in recent years are introduced.The cognition history of the theoretical model of soil conductivity has been summarized,the influence mechanism of DC and AC stray current on soil resistivity has been systematically explained,and the nonlinear change characteristics of soil resistivity under the action of AC and DC current has been summarized.At the same time,the recent research progress of the temperature correction model of soil resistivity is introduced,and the development trend in this field is prospected.
