Abstract

In practice, the shear vane test is used to predict the undrained shear strength of remolded and undisturbed clay soils. The undrained shear strength could also be estimated for remolded soils by the fall cone test. However, the determination of undrained shear strength by this test requires a very significant factor which is referred to as fall cone factor. The drained internal friction angle could be obtained by using the fall cone factor, calibrated in accordance with experimental results and the values of undrained shear strength calculated for different water contents and void ratios at critical state. In this study, compressibility and strength parameters were determined practically on remolded samples of cohesive soils with different index proporties by using the methods proposed in the literature. In addition, the applicability of the method used was evaluated for the same soil by comparing the compressibility and strength parameters obtained from oedometer and triaxial compression tests.

Abstract

Yoğrulmuş ve örselenmemiş killi zeminlerin drenajsız kayma mukavemeti pratik olarak veyn deneyi ile belirlenebilmektedir. Diğer bir pratik deney olan düşen koni deneyi ile de yoğrulmuş kohezyonlu zeminlerin drenajsız kayma mukavemetine geçiş yapılabilmektedir. Ancak bu geçiş sırasında bir düşen koni faktörüne (K) ihtiyaç duyulmaktadır. Deneysel verilerle kalibre edilen koni faktörü, farklı su muhtevaları için hesaplanan drenajsız kayma mukavemetleri ve kritik durumdaki boşluk oranları kullanılarak drenajlı kayma mukavemeti açısına geçiş yapılmaktadır. Bu çalışmada, yoğrularak hazırlanan farklı endeks özelliklere sahip kohezyonlu zemin örnekleri üzerinde, literatürde önerilen yöntemlerden faydalanılarak sıkışabilirlik ve mukavemet parametreleri pratik olarak belirlenmiştir. Aynı zeminler için ödometre ve üç eksenli basınç deneylerinden ile elde edilen sıkışabilirlik ve mukavemet parametreleri ile karşılaştırılarak uygulanan yöntemin kullanılabilirliği değerlendirilmiştir.
