Abstract

In this paper, the results of the direct shear interface friction test is introduced to understand interface friction between geosynthetic materials that are required for analyzing slope stability of the liner system of waste landfills. Tensile stresses that occur in a liner system due to differential settlement with waste load are estimated using FLAC. It was shown that HDPE/geocomposite inteface friction angle is 11.9$^{\circ}$, HDPE/wastes is 12.0$^{\circ}$ and geotextile/wastes is 28.0$^{\circ}$. Tensile stress due to settlement in a foundation of landfill is well within the limits of tensile strength regulated by waste treatment law.
