Abstract

In engineering applications, information obtained during soil explorations may be limited due to the difficulties encountered in sampling, testing and the costs involved. So, it is useful to determine properties of soils by using a small number of soil parameters that can be obtained easily. In this study the correlations between the SPT-N value and undrained shear strength (cu) are examined and developed for types of fine-grained soils based on Standard Penetration Test (SPT) corrections and test type considered statistically, and comparisons are made with previous studies. It is observed that while the correlations proposed by Terzaghi and Peck (1967), commonly used in practice, and Stroud (1974) are compatable with those proposed by the current study, those proposed by the others have given quite high results.

Özet

Mühendislik uygulamalarında numunelerin elde edilmesi, deneylerin yapılması ve maliyet giderleri yüzünden bir çok yönüyle elde edilen bilgiler sınırlı kalmaktadır. Bu nedenle mümkün olduğu kadar az ve kolay elde edilebilen zemin parametreleri kullanarak, zeminlerin mühendislik özelliklerini belirleyebilmek avantajlı olacaktır. Bu çalışmada SPT-N değeri ile drenajsız kayma mukavemeti (cu) arasındaki ilişkiler, Standart Penetrasyon Deneyi (SPT) düzeltmeleri ve deney tipinin etkisi dikkate alınarak, ince daneli zemin grupları için araştırılmış ve daha önce yapılan çalışmalarla karşılaştırmalar yapılmıştır. Özellikle pratikte yaygın olarak kullanılan Terzaghi ve Peck (1967) ve Stroud (1974)'in önerdiği bağıntıların, bu çalışmada bulunan bağıntılarla uyumlu olduğu gözlenirken diğer araştırmacılar tarafından önerilen bağıntıların ise oldukça yüksek sonuçlar verdikleri gözlenmiştir.
