| 1 | 饱和黏土高压压缩特性的微观机制——研究现状与思路显示文摘通过归纳分析发现,适用于描述常压条件下黏土压缩特性的扩散双电层理论和不平行板模型均不能对高压条件饱和黏土的双线性压缩特性进行解释。将黏土的孔隙划分为团聚体间、颗粒间及颗粒板内三层面可很好地对饱和黏土的高压压缩过程进行定性描述:高压条件下,除团聚体间及板间扩散双电层两部分的自由水分子的排出外,晶层间规则排列的结合水分子也将被逐层挤出。而该小间距条件下,基于扩散双电层机制的理论解释已不再适用,且由于水分子与晶层间的特殊结合,其他Non-DLVO作用力的出现亦必须重新加以考虑。基于此,提出了从理论上利用格子密度泛函理论描述黏土矿物界面外水分子的特殊结合形态,并嵌入该格子模型于分子动力模型中,从分子尺度研究高压条件下水-界面间的相互作用,从而最终建立基于分子层面黏土高压压缩本构关系的新思路。 | 况联飞 周国庆 Conrad Boley 邹亚洲 商翔宇 | 2013 | 煤炭学报2013，38，2： | 7 |
| 2 | Compressibility of fine-grained soils subjected to closed-system freezing and thaw consolidation显示文摘In order to investigate the effects of freezing and thawing on the compressibility of fine-grained soils, freezing and thawing tests and subsequent compression tests with fine-grained soils in an oedometer were carried out. During the freezing, a part of the soils is loosened and another part is over-consolidated under the freezing pressure σE. The compression curves after the freezing and thaw consolidation are neither different from the normal consolidation curve nor from the rebound curve of an unfrozen soil, until the consolidation pressure σz = σE is arrived. Based on the experimental results, a theoretical model has been devel- oped to predict the frost heaves, the thaw-settlements and the compressive deformations of fine-grained soils after the thaw consolidation. The theoretical results are very close to the experimental results. | BOLEY Conrad | 2009 | Mining Science and Technology2009，19，5： | 5 |
