다양한 측정방법을 적용한 대지의 전기적 구조해석

Wenner 4-probe arrangement is used most widely by the method to measure soil resistivity and the measured data with the Wenner method are apparent resistivities of the soil. Therefore, the soil structure can be analyzed easily from the measured apparent resistivity, but the real soil resistivity is difficult to know correctly at a particular depth or at a specific location on earth surface. This paper introduces a method that can be used to decide the suitable burial depth and the electrode scale of a grounding rod effectively using soil structure analysis equipment based on the dipole-dipole method.
