软土微细观结构特征的CT实验分析
Soft soil microstructure character analysis with CT
本文利用CT技术对不同深度的软土进行了观测，结合扫描电镜（SEM）与压汞法对各层土样的微细观结构特征进行了分析。CT图像是土样微结构的综合反映，扫描电镜可以进一步揭示CT图像每个体素的内部结构；CT图像的灰度值可以反映出土样中孔隙度的变化，灰度值方差体现土样内部结构的均匀性。
In this paper, CT technique is applied to observe soft soil of different depth , and microstructure characters are analyzed combined with scanning electronic microscope(SEM) and mercury instrusion method. CT images comprehensively reflect the soil microstructure, while every voxel of CT image can be observed with SEM. CT images grey value can reflect the porosity variance, and grey value variance express homogeneity of soil microstructure.
