Shear strength testing on a GCL

Study of the internal shear strength of geocomposite clay liner has been performed. Laboratory testing program consisted of several one-dimensional swelling and consolidation tests and five series of direct shear tests. Influence of the specimen hydration procedure and horizontal displacement rate on the shear test results has been determined. Shear strength criterion and the appropriate laboratory testing procedure are proposed. The results also demonstrate that the direct shear tests on nonreinforced GCLs can be performed with a modified standard direct shear testing equipment, thus avoiding the need for the substantial investment in a specialized apparatus.
