| 摘 要： | 以不同含水率的高压实钠基膨润土为对象,在自行研制的装置上开展了热-湿耦合模拟实验。结果表明：缓冲材料内的温度梯度随加热功率的加大而增大,随湿度和密度的加大而减小;缓冲材料中心温度即加热棒表面温度与某一径向点的温差与加热功率之间呈线性关系,各点处的斜率与其径向距离的对数呈线性关系。 |
| 关 键 词： | 高压实缓冲材料 钠基膨润土 热-湿耦合实验装置 温度场 |

| 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. |
| Keywords: | highly compacted buffer material Na-bentonite experimental equipment of thermo-hydro coupling temperature field |
