| 摘 要： | 对于高放废物的最终处置，深地质处置被国内外公认为最合适的方法，而膨润土也被认为是高放废物处置库缓冲回填材料的良好基质。鉴于膨润土各项性质研究的重要性。本文介绍了利用盐溶液法进行非饱和膨润土水分特征曲线的测定工作，发现盐溶液法适合测定吸力极高的非饱和土，是一种值得推广的方法。

| Abstract: | Deep geological disposal is regarded as a most suitable method to disposal the high-level radioactive waste(HLW) in the world. And bentonite base material is also regarded as suitable beffer and backfill material in this system. It is very important to study the various performances of bentonite in order to ensure the safety of HLW repository. The determination of the moisture characteristic curve of unsaturated bentonite with saturated salt solution method is introduced in this paper. The results show that the salt solution method is suitable to the unsaturated soils with high suction. |
