Abstract

Zeminin kayma mukavemeti, yapının göçmesine neden olan önemli bir faktördür. Zemin üzerine herhangi bir mühendislik yapısı inşa edilmeden önce, yapısal çökme felaketini en aza indirmek için kesme mukavemeti özelliklerinin derinlemesine araştırılması gerekir. Bu çalışma, farklı ince daneli toprak içerik yüzdelerinin zeminin kesme mukavemeti parametreleri üzerindeki etkisini açıklamaktadır. Çalışılan zemin örnekleri esas olarak kumlu ve killi topraktır. Bu araştırma, ince tanelerin kesme mukavemeti parametreleri (sürtünme açısı ve zeminin kohezyonu) üzerindeki etkisini araştırıyordu. Bu çalışmada, literatürde yer alan birçok makale gözden geçirilmiştir. Farklı makalelerden elde edilen sonuçlara dayanarak, zeminde bulunan ince zemin içeriğinin kesme mukavemeti parametrelerini nasıl etkilediğini açıklamak için akış şeması oluşturulmuştur. Kumlu zemin için, kesme mukavemeti parametreleri, karışımın sahip olduğu ince tanelerin yüzdesine ve ince mineralojik bileşimin tipine büyük ölçüde bağlıdır. Killi zeminde ince tane içeriği ve katkı maddesi arttıkça, zemin kesme mukavemeti parametrelerinin her ikisi de önemli ve görünür bir oranda artar.

Effect of Fine Content on Shear Strength Parameters of Soil

Abstract

The shear strength of the soil is a crucial factor in the structure's failure. Before any engineering structure is built on the soil, the shear strength characteristics must be thoroughly examined in order to reduce the calamity of structural collapse. The current study investigates the influence of varied percentages of fine material on soil shear strength. The soil sample consists primarily of sandy and clay soil. The study looked into the impact of fines on shear strength metrics (friction angle and soil cohesion). Several journal papers and articles were reviewed for this study. Based on the findings of several papers, the flow chart was created to describe the effect of the percentage of fine content in the soil and how it affects shear strength parameters. The shear strength parameters of sandy soil are significantly dependent on the percentage of fines in the mixture and the type of fine mineralogical composition. Both soil shear strength parameters increase at a substantial and apparent pace as compared to the particle content and additive increases in clay soil.
