The undrained shear strength behavior of sand soils with fines is affected by the initial conditions after consolidation as well as the fine grain content, void ratio variation and mean effective stress level. Therefore, in order to evaluate the behavior of soils containing fine grain, more parameters should be considered compared to clean sand. Critical state soil mechanics (CSSM) is a appropriate framework to understand the behavior of this soil types with considering all of the effective parameters. In this study a series of undrained static triaxial tests were carried out on sand-silt mixtures containing 10%, 20%, 30%, 40% and 50% fine contents at an effective consolidation pressures of 50 kPa, 100 kPa and 200 kPa. The experimental results show that undrained shear strength behavior and steady state line (SSL) are significantly affected by the fine grain contents. It was observed that up to a threshold fine content the location of the SSL moves downward from the clean sand position and beyond that, it move upward with the increase of the fine content. This shows that the shear strength behavior and compression tendency of the samples change with the change of the fine grain content. However, it was observed that the steady state parameter (Mss) and the mobilized friction angle (φss) values in steady state were also affected by the fines content.
İnce dene içeren kum zeminlerin drenajsız kayma dayanımı davranışı konsolidasyon sonrası başlangıç koşulları yanısıra, ince dane içeriği, boşluk oranı değişimi ve ortalama efektif gerilme düzeyinden etkilenmektedir. Dolayısı ile ince dane içeren zeminlerin davranışlarının değerlendirilmesi için temiz kuma göre daha fazla parametre ele alınmalıdır. Kritik durum zemin mekaniği (CSSM), tüm bu parametreleri göz önünde bulundurarak bu zemin türlerinin davranışını anlamak için uygun bir çerçevedir. Bu çaşışmada %10, %20; %30, %40 ve %50 ince dane içeren kum-silt karışımı örnekleri üzerinde 50 kPa, 100 kPa ve 200 kPa efektif konsolidasiyon basınçları altına bir dizi statik üç eksenli basınç deneyleri gerçekleştirilmiştir. Deneysel sonuçlar, örneklerin drenajsız kayma dayanımı davranışlanının ve durağan durum çizgisinin (SSL) ince dane içeriğinden önemli ölçüde etkilendiğini göstermektedir. Belirli bir eşik ince dane içeriğine kadar durağan duzum çizgisi (SSL) konumunun temiz kum konumundan aşağıya doğru hareket ettiği ve bu değerin ötesinde, ince içeriğin artmasıyla yukarı doğru hareket ettiği görülmüştür. Bu da ince dane içeriğinin değişimi ile birlikte örneklerin kayma dayanımı davranışının ve sıkışma eğiliminin değiştiğini göstermektedir. Bununla birlikte durağan durum parametre (Mss) ve durağan durumundaki mobilize sürtünme açısı (φss) değerlerinin de ince dane içeriğinden etkilendiği görülmüştür.
