摘要
本文研究了我国高放废物地质处置库缓冲 /回填材料———内蒙古高庙子膨润土的压实、膨胀力和膨胀变形特性。实验结果表明 ,膨润土样品的压实密度与压制压力和蒙脱石含量有关 ,膨胀力与样品压实密度和蒙脱石含量有关 ,样品在荷载作用下膨胀变形明显减小。
The compactibility, swelling pressure and swelling deformation property of Gaomiaozi bentonite as buffer/backfill material for HLW repository in China are studied. The test results show that the density of compacted bentonite samples are related with compaction pressure and montmorillonite content in bentonite, the swelling pressure is related with density of compacted bentonite and montmorillonite content in bentonite, and the swlling deformation is obviously reduced when the samples are under the pressure.
