Abstract

Securing the stability of waste landfill is very important of environmental and economic side. In order to secure the stability of waste landfill, slope stabilization is essential. In addition, slope stability is strongly influenced by the contact shear strength of geosynthetics used as barrier wall, so accurate contact shear strength between two interfacial materials can be an important factor for designing with landfills. Therefore, in this study, the friction characteristics on the fixed slope angle were analyzed by considering the actual application environmental condition between geomembrane and geotextile used in waste landfill. The friction characteristics between nonwoven geotextile and smooth type geomembrane increased as the slope angle increased. On the other hand, the frictional characteristics between nonwoven geotextile and textured type geomembrane tended to decrease with slope angle. Also, textured type geomembrane showed about 3 times higher frictional stresses than those of smooth type geomembrane, and textured type geomembrane was more affected by the slope angle.
