dc.description.abstract모래에 혼합된 점토의 혼합비에 의한 투수계수와 압밀계수의 영향분석을 위해 주문진 표준사와 오타와 모래에 카올린 점토를 다양한 혼합비로 섞은 시료를 제작하여 연성벽체투수시험을 실시하였다. 시험결과 시험이 실시된 10%에서 29%의 카올린 점토 혼합범위에서는 세미 로그 그래프 상에서 점토의 혼합비와 투수계수 및 압밀계수가 "반비례하는 선형적 상관관계를 나타내었다. 또한 투수계수와 압밀계수는 흙의 구조에 의해서 결정되는 것으로 나타났다. 점토비가 낮아 안정구조로 볼 수 있는 혼합토에서는 점토질 토사에서 투수계수 및 압밀계수와 높은 연관성을 가지고 있는 것으로 알려진 간극비와는 상호관계를 나타내지 않은 반면, 부유구조에서는 간극비의 증가에 따라서 투수계수가 감소하는 것으로 나타났다.Evaluation of permeability and coefficient of consolidation of clayey sand is critical in analyzing ground stability or environmental problems such as prediction of pollutant transport in groundwater. In this study, permeability tests using a flexible wall permeameter are performed to derive the coefficient of consolidation and permeability of reconstituted soil samples with various mixing ratios of kaolin clays and two different types of sands, which are Jumunjin and Ottawa sands. The test results indicate that the coefficient of consolidation and permeability plots linearly against clay contents in semi-log scale graphs for low clay mixing ratios ranging between 10 to 30%. It is also demonstrated that coefficient of consolidation and permeability of sand and clay mixture are dependent on the soil structure. Contrary to previous findings, the permeability is shown to be independent of the void ratio at low mixing ratios, which can be classified as non-floating fabric. The permeability decreases with the void ratio for floating fabric.en_US
