黏性土的工程特性，都与土体的微观结构有着密切的联系。大量的研究表明，微观结构的变化，决定了土体宏观力学性质。因此，研究黏性土工程特性与其微观结构状态之间的内在联系，对于深入研究黏性土工程特性具有十分重要的工程意义。本文选取大连市某钻孔不同深度的5个土样样品首先进行模拟原状样压缩试验（主要还是针对扰动样），分析不同荷载下的释水量和变形量，试验完成后，对原状样和压缩土样采用电子显微镜扫描（SEM），然后利用ERDAS软件对SEM图片进行分析，研究压缩前后土体微观结构，特别是孔隙大小和颗粒相关指标变化规律，结合压缩试验数据，分析二者之间的联系。

The engineering properties of cohesive soil,and is closely related to the microstructure of soil. A large number of studies have shown that the change of microstructure,determines the macroscopic mechanical properties of soil. Therefore,the engineering properties of cohesive soil with its microscopic structure state,and the inner link between for further study of engineering properties of cohesive soil has very important engineering significance. This article from a different drilling depth of simulating 5 samples of soil sample in Dalian about conducting a simulating compression test ( mainly in view of the sample disturbance),and the analysis of the water release under different load and deformation. After completion of the test,the sample and compressed soil samples scanned by electron microscopy( SEM),and then use ERDAS software to analyze the SEM images,research of soil microstructure before and after compression,especially the change law of pore size,combined with compression test data,analyzing the relationship between the two.
