The interfacial friction properties of GCL and geomembrane under different hydration conditions are discussed. In addition, the ionic solubility of hydration solution, the size of hydration normal stress and test conditions will affect the shear strength of GCL. In this paper, the friction properties of GCL upper geotextile and geomembrane interface are discussed from the following aspects: ① hydration solutions with different ionic concentrations (deionized water, 0.05mol/l CaCl2 solution and 1: 1 ethanol solution by volume); ② different types of hydration solutions (0.05mol/l CaCl2 solution and 1: 1 ethanol solution by volume); ③ different hydration normal stress conditions (pressureless hydration condition, 5kPa hydration condition and 10kPa hydration condition).
