Son yıllarda yumuşak zeminlerin iyileştirilmesi için kullanılan taş kolonun kullanımını artırmak için geogrid kaplama kullanılmaktadır. Bu çalışmada, geogrid kaplamanın, yumuşak zemin yatağı içerisindeki taş kolonun performansına olan etkisi araştırılmıştır. Geogrid kaplı ve geogridsiz taş kolonun davranışını belirlemek için deneysel ve numerik çalışmalar gerçekleştirilmiştir. Deneysel çalışma için küçük ölçekli laboratuvar testleri gerçekleştirilmiştir. Ayrıca, geoteknik mühendisliğinde iki boyutlu deformasyon ve stabilite analizleri için tasarlanmış sonlu elemanlar programı olan PLAXIS numerik çalışmalar için kullanılmıştır. Numerik çalışmalar gerçekleştirilmeden önce deneysel çalışmaların ve numerik analizlerin uyumluluğu kontrol edilmiştir. Uyum elde edildikten sonra taş kolonda geogridin rijitliğinin, geogrid kaplama boyunun ve yanal genişleme gibi farklı parametrelerin etkisi numerik çalışmalar ile araştırılmıştır. Ek olarak grup kolonlar da incelenmiştir. Bu çalışmanın sonuncu olarak, geogridin kaplama boyu ve rijitliği geogrid kaplı taş kolonun yük taşıma kapasitesini ve genişleme davranışını önemli ölçüde etkilemektedir.

In recent years, geogrid encasement has been used to extend the utilization of stone columns to improve soft soil’s properties. This paper investigates the influence of geogrid encasement on the performance of stone columns in soft clay deposits. Experimental and numerical studies were conducted to figure out behavior of stone columns with and without geogrid reinforcement. The small scale laboratory tests were carried out. In addition, PLAXIS which is a finite element package intended for the two dimensional analysis of deformation and stability in geotechnical engineering was used to numerical studies. Before conducting the numerical studies, the validation between results of the experimental studies and numerical analysis was performed. After validation, the numerical studies were performed with different parameters such as the rigidity effect of geogrid, depth of geogrid reinforcement and lateral bulging of the stone columns. In addition, group of stone column was investigated. As a result of this studies, load carrying capacity and bulging behavior of the geogrid encased stone column was significantly influenced from the depth and the stiffness of the geogrid.
