Shear Strength between Soil/Geomembrane and Geotextile/Geomembrane Interfaces

A series of laboratory tests was carried out to investigate the shear strength between geomembrane/geotextile and geomembrane/soil interfaces. These tests were conducted with a new test method which enabled repeating shear strength between soil body and cover system components under various normal stresses. The reduction of peak and residual shear strengths of the interface were investigated by conducting the test repeatedly on a same geomembrane/geotextile interface under constant normal stress. The stacking process of the landfill was simulated by testing interface samples under increasing normal stresses. The analysis results obtained from the tests demonstrate significant variation of the interface strength.
