摘　　要：本文通过红粘土电镜资料研究贵州红粘土微观结构,印证了其微结构是复杂的二重空间结构,并运用SPSS数据分析软件,对贵州七个地区1858组土工实验数据进行统计分析,研究红粘土的孔隙性指标在水平方向上的分布规律及深度方向上的变化规律,得出贵州红粘土孔隙性指标在水平横向的总趋势为由西向东逐渐减小;水平纵向孔隙指标北部由北向南孔隙指标呈现减小趋势,南部由北向南孔隙指标亦呈现减小趋势;而在剖面深度方向孔隙性指标由上至下呈增大的趋势。In this paper,it studies the microstructure of red clay by using red clay electron microscope data,confirming that its microstructure is a complex dual space structure,1858 groups of experiment data of seven regions in Guizhou are statistically analyzed by using SPSS data analysis software,and the distribution in horizontal direction and the changing rule of the depth direction of the porosity index of the red clay are studied,it is concluded that the general trend of the porosity index of Guizhou red clay in the horizontal direction is gradually decreasing from west to east.The horizontal vertical pore index shows a decreasing trend from north to south,the pore index also shows a decreasing trend from north to south in the south area,in the depth direction of the profile,the porosity index shows an increasing trend from top to bottom.
