Shear strength parameters between geomembranes and cohesive soils
AbstractThis paper focuses on the shear strength of various geomembranes and a number of different cohesive soils. The data base is felt to be necessary since geomembranes used in solid waste disposal are often placed directly on low permeability clay soils. Adapted direct shear tests were performed allowing for a determination of adhesion and friction angle values. It was seen that the adhesion of the soil to the geomembrane is significantly reduced from the cohesion value of the soil itself, unless the geomembrane is very soft or textured. Conversely, the friction angle at the interface between the geomembrane and the soil is relatively high, at least for the normal pressures used in these tests. The information presented is felt to be the type necessary for a number of practical design considerations.
