... mechanisms: interlocking and friction. For geotextile/geomembrane and drainage geocomposite/geomembrane interfaces, the higher the asperity height, the higher the interface shear strength. Whereas for soil/geomembrane interfaces, the higher the soil shear strength, the higher the interface shear strength...

... contents of as-received (19%), 50 and 100%. Both peak and large-displacement (50 mm) shear strength parameters were determined. For cover liners, temperature was determined to have a greater influence on interface shear strength than moisture content, whereas bottom liner shear strength was influenced more...

...) unconstrained geotextile configuration The shear box measures 10.2 cm wide by 10.2 cm long by 5.1 cm high. While current practice recommends using a 300 mm by 300 mm square shear box, there is still not agreement about the effect of shear box size on evaluating the interface shear strength...

...N. Dixon; D. R. V. Jones; G. J. Fowmes Failure of modern landfills by slippage of lining materials and waste bodies is not uncommon. The majority of failures are controlled by slippage at interfaces between lining components. Information on variability of interface shear strength is required both...

...P. Chiu; P. J. Fox This paper presents information from a large database that has been compiled on internal and interface shear strengths of geosynthetic clay liners (GCLs). The data were obtained from the literature, GCL manufacturers, and the authors' own tests, and are representative of the most...
