Bu çalışmada, kumlu zeminler üzerine oturan şerit temellerin taşıma kapasitesi sayısal ve teorik olarak analiz edilmiştir. Bu amaçla, kum zemine oturan bir şerit temel modeli oluşturularak üç boyutlu Plaxis3D bilgisayar programı ve literatürdeki mevcut teorik yöntem (Terzaghi Yöntemi) kullanılarak analizler gerçekleştirilmiştir. Sayısal analizlerde, farklı temel genişlikleri kullanılarak, temel genişliğinin, taşıma kapasitesi, qu ve taşıma gücü katsayısına, Nγ etkisi incelenmiş ve teorik yöntemle karşılaştırmalar yapılmıştır. Sayısal analiz sonuçları, temel genişliğinin artmasıyla şerit temelin taşıma kapasitesinin arttığını, taşıma kapasitesi katsayısının ise azaldığını göstermiştir

Effect of Footing Dimension on the Bearing Capacity of Shallow Foundations on Sand

Öz

In this study, the bearing capacity of strip footings on sand was investigated numerically and theoretically. For this aim, a strip footing model on sand was constituted and analyses were performed using Plaxis-3D computer program and theoretical method (Terzaghi Method) from the literature. In the numerical analysis, the effect of footing width on the bearing capacity, qu and the bearing capacity factor, Nγ was investigated using different footing widths. The numerical results indicate that with increasing footing width, the bearing capacity of strip footing is increased, while the bearing capacity factor is reduced
