摘要：Interaction behavior of soil-geosyntheticsystem is of great importance in design and analysisof reinforced soil structures. Type of soil andgeosynthetic influence the parameters describing theinteraction. In general, interaction parameters of soilgeosyntheticsystem are generally determined bydirect shear and pullout tests. This paper presents theinfluence of different types of soils and geosyntheticson the interaction behavior of soil-geosyntheticssystem using direct shear tests. Large scale directshear tests were conducted for the purpose using fourdifferent types of cohesionless soils and two types ofgeosynthetics (woven and nonwoven). The results arepresented and discussed in terms of peak shearresistance, interface friction angle and efficiencyfactors for different soils and geosynthetics. It isobserved that the interface friction angle values aresignificantly affected with soil type and geosyntheticmaterial. Efficiency factors are not affected with typeof soil for a selected geosynthetic material. However,different efficiency factors for different geosyntheticmaterials are observed. For the range of materialstested at the 50 kPa normal stress the range ofefficiency factors is 0.4-0.45.
