Abstract

Soils, classified according to their grain sizes, are generally in a mixture in various proportions in the nature. In this study, shear strength properties of clayey gravel samples which prepared in three different compositions were investigated with large scale direct shear tests. In order to investigate soil type, particle size, shape and roughness effects on shear strength properties, samples containing various grain sized gravel and kaoline clay were prepared and experiments were conducted in saturated condition. The results have shown that, crushed stone sample containing bigger grain size had 10% bigger internal friction angle than sample in same composition. It was observed that, crushed stone had 16% bigger internal friction angle than gravel sample prepared in same composition and grain sized.

Özet

Belirli dane boyutlarına göre sınıflandırılan zeminler doğada genellikle çeşitli oranlarda karışım halinde bulunmaktadır. Bu çalışma kapsamında 3 farklı kompozisyonda hazırlanmış kil - çakıl numunelerinin kayma mukavemeti özellikleri büyük ölçekli direk kesme deneyleriyle incelenmiştir. Çakıl türünün, dane boyutunun, şeklinin ve pürüzlülüğünün kayma mukavemeti üzerindeki etkisinin incelenmesi amacıyla çeşitli dane dağılımına sahip kırmataş ve dere çakılları kaolin kiliyle belirli kompozisyonlarda karıştırılarak numuneler hazırlanmış, doygun durumda deneyleri yapılmıştır. Deneyler neticesinde kırmataş içeren aynı kompozisyondaki iki numuneden, iri dane dağılımlı numunenin %10 oranında daha büyük içsel sürtünme açısına sahip olduğu belirlenmiştir. Aynı kompozisyon ve dane dağılımına sahip iki numuneden kırmataş içeren numunenin, dere çakılı içeren numuneden %16 daha büyük içsel sürtünme açısına sahip olduğu belirlenmiştir.
