摘要

The hydraulic conductivities of water saturated Ca--bentonite with dry densities of l .4, l.6, and l .8 Mg/m~3 were measured within the temperature range of 20 to 80deg.C. The hydraulic conductivities of all the compacted bentonites are lower than l0~-11 m/s, and the relationship between the logarithm of the hydraulic conductivity and the bentonite dry density can be fitted to a straight line. The hydraulic conductivities of bentonites increase with increasing temperature, and the hydraulic conductivities at 80deg.C increase up to about three times those at 20deg.C. The measured values are in agreement with those predicted from the hydraulic conductivities at 20deg.C assuming that only fluid properties are changed with changing temperature. The change in viscosity of water with increasing temperature contributes greatly to the increase of hydraulic conductivity.
