近 10 a 来,用于高放废物工程屏障的高压实膨胀黏土的性状受到了广泛关注。据此通过吸力控制试验获取了一些高压实膨润土的试验数据,并从微观结构特性角度进行了解释。水分滞留和迁移特性,以及吸力变化下的膨胀反应都与微观机理相关,同时对吸附阳离子的作用也进行了评价。
In the recent 10 years, the properties of high-pressure solid expansive clay used for high-level radioactive waste engineering barriers have drawn much attention. Based on this, some experimental data of high-pressure bentonite were obtained through the suction control test and the microstructure characteristics were explained. Moisture retention and migration characteristics, and the expansion reaction under changes in suction are all related to the microscopic mechanism, and the role of the adsorbed cations is also evaluated.
