Abstract
Temeller, çok sayıda inşaat projesinin önemli bir parçasıdır. Yapısal yüklerin yüzeysel temellerle güvenli bir şekilde taşınamadığı durumlarda, kazıklar veya kazıklı temeller kullanılır. Bu çalışmada radye ve kazıklı radye temellerin taşıma gücü ve oturmasının belirlenmesi incelenmesi ve karşılaştırılması amaçlanmıştır. Bu amaçla bir deney düzeneği oluşturuldu; model radye ve model kazıklı radye temeller üzerine yükleme deneyleri gerçekleştirilmiştir. Sonuçlar, pahalı ve zaman alıcı saha denemeleri yapmadan, kumlu zeminlere gömülü kazıkların taşıma kapasitesinin ön değerlendirmesi ve oturması için bir referans görevi görebilir.

Abstract
FFoundations are important parts of many construction projects. Piles or piled foundations are used in the cases where the structural loads cannot be carried safely with the shallow foundations. In this study, it is aimed to investigate and compare the bearing capacity and sitting settlement of rafts and piled raft foundations. For this purpose, a test setup was formed and loading tests were carried out on a model raft and a model piled foundation. The results can serve as a reference for the preliminary assessment of bearing capacity and settlement of driven piles embedded in sandy soils without conducting expensive and time-consuming field trials.
