대지구조 변화에 따른 전극 길이별 지선형 접지전극의 접지저항 특성

The resistance to ground of vertical electrodes buried in uniform and two-layer soils structure has been analyzed for a length of electrodes and soil parameters. The equation of ground resistance of vertical electrodes are Tagg’s equation for uniform soil models, and modified equation of Dwight equation for two-layer soil model. In this paper, compared with results of two equations are calculated values of vertical electrode in uniform and two-layer soil models.
