Abstract

In this study, bearing capacities, settlement and stress behavior were determined for a shallow circular foundation inside and outside of a shear plane under eccentric loading conditions. For this purpose, unreinforced and reinforced slope models which were safe against collapsing, were used. Geogrids were fixed at some predetermined depths inside the slope. Loading values, displacements and additional vertical stress values which occurred as a result of the circular footing were measured by means of load cells, displacement transducers and pressure transducers, respectively. Finally, it was identified that eccentricity had an important effect in the determination of bearing capacity and soil stresses.

Özet

Bu çalışmada, dairesel bir temelin, şevin göçme yüzeyi içinde ve dışında inşa edilmesi durumunda meydana gelen taşıma gücü, oturma ve gerilme davranışları, eksantirik yük etkisinde araştırılmıştır. Bu amaç doğrultusunda, donatısız ve donatı ile güçlendirilmiş göçmeye karşı güvenli şev zemin modelleri kullanılmıştır. Şevli zemin içerisine belirlenen derinliklere geogrid donatı yerleştirilmiştir. Dairesel temelden dolayı meydana gelen yük değerleri, oturmalar ve ilave düşey gerilme değerleri sırasıyla yük hücresi, deplasman ölçerler ve basınç algılayıcıları yardımıyla ölçülmüştür. Sonuçta, eksantirisitenin hem taşıma gücü hem de zemin gerilmeleri üzerinde önemli bir etkisinin olduğu belirlenmiştir.
