DERİN ZEMİN KARIŞTIRMA YÖNTEMİYLE İYİLEŞTİRİLEN ORGANİK ZEMİNLERİN DAYINIMI

Öz

Derin karıştırma yöntemi bağlayıcı kullanılarak zeminin mukavemet ve oturma gibi özeliklerinin iyileştirilmesi için kullanılan zemin iyileştirme yöntemlerinden birisidir. Organik zeminlerin su muhtevası, pH, organik yüzdesi ve içerdiği organik maddeler nedeniyle bu iyileştirme işlemi daha da zorlaşmaktadır. Bu çalışmada zemin derin karıştırma yönteminin organik zeminlerde uygulanabilirliğini ve ona etki eden parametreleri değerlendirmek amacıyla literatürde yer alan on beş ayrı çalışma incelenmiş ve toplamda 224 veri elde edilmiştir. Bu veriler su muhtevası, kullanılan bağlayıcı çeşidi, dozaj ve içerdikleri organik yüzdesi açısından serbest basınç mukavemetiyle olan ilişkileri incelenmiştir.

STRENGTH OF ORGANIC SOILS IMPROVED BY DEEP SOIL MIXING METHOD

Öz

Deep mixing method is one of the methods used to improve the properties of soil such as strength, permeability and compressibility by adding binder. The improvement process becomes more challenging when dealing with organic soils due to their water content, pH, organic content, and presence of organic matter. This study aims to evaluate the applicability of the deep soil mixing method in organic soils and assess the parameters that influence it. A total of 224 data points were obtained from fifteen individual studies to analyses the relationships between the data, including water content, type of binder used, dosage applied, and their respective organic percentages, with the unconfined compressive strength. As a result of the study, the increase in water content and organic percentage caused a decrease in the strength values, and the increase in the amount of binder used led to an increase in the strength values. As a result, when the right conditions are met, it is possible to reach the values offered by FHWA for the deep mixing method in organic soils as well as inorganic soils.
