Abstract: The hydraulic tests were conducted on the geo-synthetic clay liners (GCLs) containing granular or powdery Na-bentonite under various temperatures and solutions by using GDS geoenvironmental permeameter. After hydration with 0.05 mol/L CaCl2 solution, the hydraulic conductivity of GCLs sample showed an upward trend with the increase of temperature. Taking deionized water as hydration solution, the hydraulic conductivity of granular bentonite GCLs decreased with the increase of temperature, while the hydraulic conductivity of powdery bentonite GCLs increased with the increase of temperature. The content of adsorbed water of bentonite decreased in deionized water with the increase of temperature, and the absorbed water was much lower in CaCl2 solution. In a given CaCl2 solution, the swelling index of bentonite increased slightly with temperature. When the temperature was constant, the swelling index decreased significantly with the increase of CaCl2 concentration. In the case of deionized water, the variation of hydraulic conductivity with temperature is mainly affected by the amount of montmorillonite gel, followed by fluid viscosity coefficient and the absorbed water content. The more heterogeneous pore structure of granular bentonite with deionized water is, the more significant the amount of gel montmorillonite is,resulting in the decrease of hydraulic conductivity and intrinsic permeability with the increase of temperature. In the case of CaCl2 solution, the variation of hydraulic conductivity with temperature is mainly affected by fluid viscosity and the amount of adsorbed water, while the effect of montmorillonite gel is weak. In conclusion, solution, temperature and bentonite form all have important influences on the hydraulic conductivity of GCLs.

Key words: geosynthetic clay liners, hydraulic conductivity, temperature effects, solution, adsorbed water, montmorillonite gel
