토양의 저항률 측정 방법의 비교 연구

Wenner 4-probe arrangement is used widely to measure soil resistivity and the measured data using the Wenner method is an apparent resistivity of soil. This method covers the equipment and procedures for the field measurement of soil resistivity. This paper introduces a method that can be used to decide the suitable formula, for sample that not field test. It was known that the method for determining the soil resistivity in ASTM is more accurate than that in IEC TC81/339/CD.
