针对西安原状黄土进行了湿陷性试验，并对湿陷前后的试样进行电镜扫描( SEM)，获取湿陷前、后黄土试样的微结构照片，进而抽取相应条件下的SEM照片的简单微结构参数。利用统计学原理中的相关分析，研究了简单微结构参数之间的相关关系。研究表明，黄土的部分微结构参数之间存在显著的相关关系，利用这些参数描述黄土的微结构特征时，存在着明显的信息重叠。这一结论为进一步构建低维合成微结构参数奠定基础。

Collapsible test of Xi’ an loess were perfomed, and the microstructure photos of before and after collapsing samples were obtained using Scan Electron Microsope( SEM) . Then original simple microstructural parameters were extracted from these corresponding condition SEM pho-tos. The Correlation among microstructural parameters were studied by using correlation analysis in statistical principle. The result shows that some simple microstructural parameters of loess are obviously correlation with others. That is, when describing the microstructural characteristics of loess using these parameters, superposition of information is clear. This conclusion can provide a base for establishing low-dimensional composite microstructural parameters.
