| 摘 要： | 通过文献调研、资料总结和分析,阐述了温度对膨润土诸多性状的影响。膨润土中孔隙水的化学成分因温度变化而发生改变,温度的增加使膨润土中内水、外水的含量发生改变,从而影响土的水合力大小。以OPHELIE膨润土实验为例,介绍了温度对膨润土内部孔隙大小的影响。此外,还对目前膨润土持水能力与膨胀力的温度效应进行了阐述。

| Abstract: | The discussion is commenced by describing the aspects related to the compacted bentonite that are influenced by temperature change.Temperature effects the chemistry of pore water of bentonite.The hydration force changes as effects of the temperature on the content of internal water and external water.Temperature effect on the pore size of bentonite is introduced by the OPHELIE experiment.And the temperature effects on the water retention and swelling behavior of compacted bentonite are described with previous investigations. |
