摘要：Geosynthetic Clay Liner (GCL) and geomembrane is a kind of geosynthetics, which are widely used in large-scale landfills, road engineering and anti-seepage engineering, but the theoretical research of the two lags behind practice. The key to the overall stability of the landfill is the strength of the GCL shear strength. GCL has two types of shear failure: one is the interface shear strength failure, and the other is the GCL internal failure. In the existing failure cases of GCL used on slopes, it has not been found that the damage of GCL occurred inside the GCL. The key to maintaining the overall stability of the landfill is to determine the interface frictional shear strength of GCL, that is, the shear strength of the interface between GCL and other geotextiles at a certain slope position becomes a key factor in stability design. In this paper, under different hydration conditions of GCL, the influence of hydration solution, normal stress under hydration and hydration time on the shear strength of the interface between GCL and geomembrane is discussed.
