대지표면상태가 대지저항률의 측정결과에 미치는 영향

초록

Generally the measured value of earth resistivity depends on the physical properties of the earth, the ground structure, the water content, and ground surface states. These physical components are affected by the climatic and seasonal factors. In this paper, the measurements of earth resistivity have been performed 1-2 times in a month by selecting different 5 points in the Sudokwon landfill, which varies ground resistivity characteristics in the large area (15,400,000m²). The earth resistivity has been measured by Wenner's four-electrode method. As a result, the earth resistivity in summer(July to September), in which the surface of the ground is moist, is lower than spring(April to June), in which the surface of the ground is dry.
