Abstract: In landfills, geomembranes are commonly placed on the slopes to isolate waste from the surrounding ground. Placement of soil cover and waste layers over these geomembranes will result the shear stress on the liners and lead to developing significant linear tensions and displacements which are necessary to be studied so as to ensure the safety use. This paper took into account the essential stress-strain compatibility and used the hyperbolic curve to model the interface shear stress-displacement between the lower interface and soil, then got the governing differential equations. The equations were solved numerically using a finite difference combined with iteration method. Finally, the important factors which influence the behavior of the interface between the geomembranes and soil, are studied.

Key words: landfill, geomembrane, hyperbolic model, finite difference method, tension, displacement
