Geotechnical Engineering Institute, Korea Institute of Civil Engineering and Building Technology, 1190 Simindae-Ro, Ilsanseo-Gu, Goyang-Si, Gyeonggi-Do, 10223, KoreaReceived 24 November 2015; received in revised form 21 December 2015; accepted 23 December 2015본 연구에서는 유류로 오염된 모래의 지반공학적 특성에 대하여 분석하였다. 오염물로 사용한 유류는 점도특성을 고려하여 등유, 원유, 자동차 엔진오일을 선정하였고, 모형지반은 주문진 표준사를 사용하였다. 실내시험은 다짐시험, 투수시험, 직접전단시험을 유류의 오염비율에 따라 수행하였다. 투수시험에서 유류의 함유비가 증가할수록 오염되지 않은 지반에 비해 투수계수가 점진적으로 저하되었다. 내부마찰각은 오염되지 않은 지반보다 상대적으로 감소하였다. 주요어 : 유류오염 , 점도, 다짐시험 , 투수시험 , 내부마찰각Contamination of soil due to an oil spill influences its subsequent behavior. An investigation was conducted tostudy the effect of oil viscosity on compaction characteristics, coefficient of permeability, and shear strength. Waterpermeability was also determined by using Kerosene, Engine oil, and Crude-oil as contaminants. The test resultsindicate that the compaction characteristics are influenced by oil contamination. Direct shear test was conducted toinvestigate the effect of oil in the pore space in sandy ground. angle of internal friction of sand (based on totalstress condition) decreases due to presence of oil within the pore spaces in sand. Key words: oil contamination, viscosity, compaction, permeability, internal friction |
