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——缓冲层在热湿耦合作用下的宏观表现,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
This paper studies the macroscopic performance of the buffer layer, the last artificial barrier in the deep geological repository of HLW, and gives some helpful revelations through self-designed experiments. It is preliminarily considered that the time involved in this study Within the range, the influence of the water potential field on the temperature field distribution in high-pressure solid bentonite is small, but the temperature field has some influence on the water migration. In this paper, the experimental design, experimental procedures, experimental results and analysis are introduced, which have certain reference value for the study of heat and mass transfer in porous media and deep geological disposal of high level radioactive waste
