METHOD OF MEASURING THE VOID RATIO OF FINE SOIL THROUGH X-RAY/CT, CAPABLE OF MEASURING THE VOID RATIO OF SOIL BY PERFORMING X-RAY/CT ON THE CENTRAL PART OF A SAMPLE

摘要

PURPOSE: A method of measuring the void ratio of fine soil through X-ray/CT is provided to enable the void ratio of soil to be easily measured using X-ray/CT even if it is impossible to visualize void through X-ray/CT images.;CONSTITUTION: A method of measuring the void ratio of fine soil through X-ray/CT is as follows. X-ray/CT is performed on a sample of standard soil to obtain images(S1). CT value is calculated on each voxel of the obtained X-ray/CT images(S2). A CT representative value for representing the area, on which X-ray/CT has been performed, is calculated from each CT value of a plurality of voxels arranged on that area(S3). The CT representative value and the void ratio of soil on the X-ray/CT images of taken soil using a corresponding X-ray/CT device are obtained. The obtaining of images, CT value and CT representative value by X-ray/CT on a plurality of kinds of standard soil sample with different void ratios is repeated to build database on CT representative value for the void ratios(S4).;COPYRIGHT KIPO 2011
