¿µ¹®³»¿ë¿ä¾à First, the 4-pole electrode method by Wenner is provided as a basis measuring mean. The calculation methods of earth resistivity about 2 stratums structure are presented utilizing the ¥ñ-a curve composed with the measured data by this basis measuring mean.
Other arranging methods of measuring electrodes and their calculation formulae of earth resistivity, the meaning of distance between electrodes as a measurement depth, the considerable effect of nearby buried conductive structure, the calculation method for multi-layered strata, and the reversing calculation method of earth resistivity from a ground resistance - all these are described in Annexes.
