【摘要】 本文系采用高宾空冷冻升华干燥法,对湖北省鄂州市太和膨胀岩和阳新膨胀岩进行了水份变化而引起的孔径分布变化规律的研究,揭示了不同含水状态下膨胀岩的孔径分布状况,为深入研究膨胀岩的胀缩过程及其与工程性质的关系提供了一个新的研究方法,预计对膨胀岩的膨缩机理研究具有理论意义。更多还原

【Abstract】 This stady makes use of methods of both controlled humidity and freeze-drying to prepare samples of swelling rocks, and then mercury intrusion porosimeter is employed to determine porosity and pore size distribution in samples. Relation between pore size distribution and swell-shrlnk of swelling rocks is discussed in detail.更多还原
