토양저항률의 측정결과에 미치는 지형의 영향

초록

Generally three electrode and four electrode fall-of-potential methods are used to obtain information of soil resistivity. This paper presents the results of the soil resistivity at different sites surveyed by the above mentioned methods. The influence of the earth surface conditions on the soil resistivity measured at the well-prepared area is nearly negligible. However, the earth surface conditions in the vicinity of watercourse have a significant effect on the soil resistivity measurements.
