Evaluating the Mechanical Behaviour of Geotextile Reinforced Sand It is important to determine the mechanical properties of reinforced soils, since they are extensively used in practice. In this study, laboratory triaxial tests and direct shear tests were carried out in order to determine the stress-strain and dilation characteristics of geotextile-reinforced river sand. The mechanical behaviour of the composite material was investigated through varying the type of geotextile and confining pressure. Interface properties of geotextile-reinforced samples were evaluated with the direct shear tests. The results demonstrated that geotextile inclusion increases the peak strength, and reduces dilation especially at higher confining pressures

Donatılı zeminlerin mekanik özelliklerinin belirlenmesi uygulamada sıkça kullanılmaya başladıklarından dolayı önem arz etmektedir. Bu çalışmada geotekstil donatılı nehir kumunun gerilme-deformasyon ve kabarma özelliklerinin belirlenebilmesi amacıyla laboratuvar üç eksenli deneyleri ve direkt kesme kutusu deneyleri gerçekleştirilmiştir. Kompozit malzemenin mekanik özellikleri geotekstil tipi ve çevresel basınç değişimleriyle incelenmiştir. Direkt kesme kutusu deneyleri ile geotekstil donatılı numunenin arayüzey özellikleri belirlenmiştir. Sonuçlar, geotekstil donatının pik dayanımı arttırdığını ve özellikle yüksek çevresel basınçlar altında kabarmayı azalttığını göstermiştir
