| 摘 要： | 膨润土被选为高放废物深层地质处置库的缓冲/回填材料,有必要研究其力学性能。使用固结仪对不同干密度和含水率的钙基膨润土进行了膨胀变形与膨胀力的试验研究。试验结果表明：膨润土的膨胀应变主要取决于膨润土的初始干密度和含水率,随着初始干密度的增加而增加,随初始含水率的增加膨胀变形逐渐减小。

| Abstract: | It is necessary to study the physical and mechanical properties of bentonite, a kind of buffer / backfill material for the deep geological disposal of high level radioactive waste. This paper, with the use of consolidometer, carries out experiments to study the swelling deformation and swelling pressure of ca-bentonites that differ in density and water content. Test results show that swelling strain of bentonite is mainly subjected to its initial dry density and water content, increasing as the initial dry density increases and decreasing as the initial water content increases. |
