Abstract

Parametric studies based on laboratory pilot tests were performed to investigate the relationships between electrical resistivity and properties of contaminated soils. Three kinds of sandy soils sampled and leachate from an industrial waste landfill were mired to model the contaminated soils. Electrical resistivity of soils was measured by using a simulated resistivity cone penetrometer probe. In the experiments. the electrical resistivity was observed by changing the water content, void ratio, unit weight, degree of saturation, and concentration of the leachate. The test results show that the electrical resistivity of soils depends largely on the water content and the electrical property of pore water rather than unit weight and types of soils.

실내모형실험으로 전기비저항치와 오염된 흙의 물리적 성질과의 상관관계를 규명하기 위해서 요소분석을 수행하였다. 세가지의 모래질 구에 산업폐기물매립지의 침출수를 첨가하여 모형실험에 이용했다. 혼합토의 전기비저항치는 비저항콘을 모사한 프로브를 제작하여 측정했다. 실내모형실험에서는 흙의 함수비, 간극비. 단위중량, 함수비 및 침출수의 농도를 변화시키면서 혼합토의 전기비 저항치를 계측했다. 실험결과는 흙의 종류 및 단위중량보다는 흙의 함수비, 간극수의 전도성이 전기비저항치에 큰 영향를 미치고 있음을 알 수 있었다.
