中文摘要：

利用河海大学自行研制的土体微细结构光学测试系统,对某坝体粘性土在压缩过程中微细结构变化进行了定量分析研究,并分析了导致该坝体填料压缩性偏高因素,提取并分析了相关微细结构特征参数,为研究粘性土压缩变形与微细结构变化间的定量关系提供了一条可行的途径。

英文摘要：

By using image processing system made by our own lab, microstructure changes in compressive procedure can be quantitatively studied and correlative characteristic parameters can be extracted and analysed; thus making it feasible to study the quantitative relation between compressive deformation and microstructure changes of clayey soils.
