摘要
Abstract
Taking highly compacted Na-bentonite materials of different water content as studying object,the simulated experiments of thermo-hydro coupling were done in a self-developed equipment.Test results indicated that the temperature gradient in bentonite increased with the increase of heat power,and decreased with the increase of moisture and density;the central temperature of buffer material,i.e.the difference that the heater surface temperature subtracts that of radial position,was linearly correlated with heat power.However,slope rate at each point was found in linear correlation with the logarithm of the radial distance.关键词
