| 摘 要： | 本文研究了作为高放废物深地质处置库最后一道人工屏障－缓冲层在热湿耦合艇下的宏观表现，通过自行设计的实验，得到了一些有益的启示，初步认为在本研究涉及的时间范围内，水势场对高压实膨润土中温度场分布影响较小，而温度场对其中水分运移有一定影响。文中介绍了有关实验设计、实验步骤，实验结果与分析，对多孔介质中传热传质研究及高放废物深地质处理有一定参考价值。．

| Abstract: | Highly compacted bentonite blocks have been heated and hydrated in the laboratory in order to simulate the conditions of buffer material in a high level radivactive waste repository.Temperature distribtuions at different times,final water content have been measured.The results show that the temperature field in little affected by hydration process,but moisture fransport in a little affected by the local thernal gradient. |

| Keywords: | deep geological disposal of high level radivactive waste hight compacted bentonite buffer material thermal hydraulic coupled process |
