Abstract

It is important to determine the mechanical properties of reinforced soils, since they areextensively used in practice. In this study, laboratory triaxial tests and direct shear testswere carried out in order to determine the stress-strain and dilation characteristics ofgeotextile-reinforced river sand. The mechanical behaviour of the composite material wasinvestigated through varying the type of geotextile and confining pressure. Interfaceproperties of geotextile-reinforced samples were evaluated with the direct shear tests. Theresults demonstrated that geotextile inclusion increases the peak strength, and reducesdilation especially at higher confining pressures.

Özet

Donatılı zeminlerin mekanik özelliklerinin belirlenmesi uygulamada sıkça kullanılmayabaşladıklarından dolayı önem arz etmektedir. Bu çalışmada geotekstil donatılı nehirkumunun gerilme-deformasyon ve kabarma özelliklerinin belirlenebilmesi amacıylalaboratuvar üç eksenli deneyleri ve direkt kesme kutusu deneyleri gerçekleştirilmiştir.Kompozit malzemenin mekanik özellikleri geotekstil tipi ve çevresel basınç değişimleriyleincelenmiştir. Direkt kesme kutusu deneyleri ile geotekstil donatılı numunenin arayüzeyözellikleri belirlenmiştir. Sonuçlar, geotekstil donatının pik dayanımı arttırdığını veözellikle yüksek çevresel basınçlar altında kabarmayı azalttığını göstermiştir.
