| 摘 要： | 缓冲材料是高放废物深地质处置多重屏障系统中非常重要的一道人工屏障，内蒙古高庙子钠基膨润土被确定为我国高放废物深地质处置缓冲材料的首选基料。通过研究该钠基膨润土（GMZ01）在不同含水量条件下的压实成型性、不同压实干密度和不同含水量压实样品的无侧限压缩性能，认为：含水量为15％的高庙子天然钠基膨润土压实成型性最好，压实干密度越大，无侧限抗压强度越大；在无侧限压缩实验时，含水量为15％的高密度压实膨润土样品比含水量为10％和20％的样品的抗压强度大，变形小。 |
| 关 键 词： | 高放废物 深地质处置 钠基膨润土 压实成型性 抗压强度 |

| Abstract: | Buffer material layer is one of the important engineering barriers in the highlevel radioactive waste(HLW) geologcal repository.Gaomiaozi bentonite deposit has been regarded as the supply base of buffer material for HLW geological repository in China.Compressibility of Gaomiaozi Na-bentonite with different water content and different compacted density has been studied.It is found that Gaomiaozi Na-bentonite with 15% water content is easily to be compacted to high density.The higher compacted bentonite has higher uniaxial strength.The compacted Na-bentonite with high density and 15% water content has high uniaxial strength and less strain. |
| Keywords: | high-level radioactive waste(HLW) deep geological disposal Na-bentonite compressibi-lity uniaxial strength |
