摘要
膨润土作为高放废物深地质处置场最后一道人工屏障──缓冲层的基材,其在高压实情况下力学性能如何,对处置场的长期安全性极为关键。进行不同含水率的高压实膨润土的单轴与三轴试验,结果表明,高压实膨润土受力时存在不可恢复的塑性变形,具一定力学强度和良好的延展性。
The expansive soil is a final man - made shield-basement material of cushion in underground site to treat waste with heavy radioactive. How its mechanical properties under high compaction is the vital to the long term safety of underground handling site. The results of uniaxial and triaxial tests for high compaction expansive soil with the different moisture content show that it has the no - recoverable plastic deformation, and the fixed mechanical strength and the good ductility.
