To investigate the unsaturated characteristics of the Boeun granite weathered soil, matric suction and volumetric water content were measured in both drying and wetting paths using Automated Soil-Water Characteristics Curve Apparatus. Based on the measured results, Soil-Water Characteristics Curve w...

불포화토의 특성을 고찰하기 위해, 어떤 조사가 필요한가? | 불포화토는 건조토(dry soil)와 포화토(saturated soil)의 중간영역으로 고전적인 포화토의 이론으로는 불포화토의 특성을 정확하게 설명할 수가 없다. 따라서 불포화토의 특성을 고찰하기 위해서는 모관흡수력 변화에 따른 불포화 지반내 간극수 보유능과 침투능의 상관관계를 조사하여야 한다. 불포화 토질역학에서 흙의 내부에 함수비 혹은 포화도에 따른 모관흡수력의 관계를 흙-함수특성곡선(Soil-Water Characteristic Curve, SWCC)이라고 하며, 불포화토의 거동을 이해하는데 가장 중요한 요소이다. | |
흙-함수특성곡선은 어디에 활용되는가? | 불포화 토질역학에서 흙의 내부에 함수비 혹은 포화도에 따른 모관흡수력의 관계를 흙-함수특성곡선(Soil-Water Characteristic Curve, SWCC)이라고 하며, 불포화토의 거동을 이해하는데 가장 중요한 요소이다. 흙-함수특성곡선(SWCC)은 불포화토 고유의 특성으로서 불포화토의 흐름특성을 이해하고 함수비에 따른 흙의 응력 및 강도특성을 해석하는데 필수적인 요소로 활용되고 있다. 따라서 불포화토의 특성을 이해하기 위해서는 실험을 토대로 불포화토의 함수비 혹은 포화도에 따른 모관흡수력을 측정하고 이를 분석하는 것이 중요하다. |
