Extensive laboratory geosynthetic interface shear testing was conducted to understand the behavior of typical bottom liner system interfaces, e.g., textured geomembrane/double-sided geosynthetic drainage composite (GMX/GDC) and textured geomembrane/non-woven geotextile (GMX/NGT), to develop the numerical model. Based upon the comparison of numerical results to experimental data, a beam element was developed to model the geomembrane. The beam element was attached to a general element in the model by interface elements to simulate static and seismic shear behavior of the geosynthetic interface, e.g., GMX/GDC.
