“…Kolonların efektif aralıkları, kolonların efektif uzunluğu, kolonların efektif çapı ve optimum kolon grubunun radyeye oranı gibi faktörler elde edilmiştir. Radye temellerde beton kazık ve derin karıştırma kolonlarının kullanımı arasında bir karşılaştırma yapılmıştır (Oliaei M.,2021). Ayrıca Geogrid katmanları ile kolon destekli dolguların (CSE), büyük deformasyonlara ve yanal hareketlere maruz kalabilen yumuşak zeminler için en etkili ve ekonomik tekniklerden biri olduğu doğrulanmıştır .…”

The deep mixing method is an in-situ soil improvement method in which the soil is mixed with cement and other binding materials. Within the scope of this study, two-dimensional numerical analyzes of a reinforced soil by deep mixing columns were carried out. Two different soft clay soil properties (Model 1 and Model 2) were used in the analyses. Analysis of two-dimensional models was done with PLAXIS 2D finite element program. The deformations, consolidation and compression obtained from Mohr-Coulomb and soft soil models were compared. The effects of soil properties and the length of the column, modulus of elasticity, diameter and distance between them were investigated for two models. As a result, it is thought that two-dimensional analyzes together with the modeling that will reflect the current site conditions can give reasonably realistic results if the soil properties are selected well and correctly before the construction phase.
