CT Tomography of Wide Gradation Gravel Soil and Its Permeability Determination
Abstract
Through CT scanning of three gravel soil samples, Avizo software was used to carry out three-dimensional reconstruction, and the porosity, specifi c surface area and tortuosity of gravel soil samples were obtained with the help of the internal algorithm of the software. The experimental data and the data obtained after software processing were respectively substituted into the Kozeny-Caman equation to calculate the permeability of gravel soil samples. Using overlapping sphere theory combined with linear path function and gravel soil itself linear path function for comparative analysis.
Keywords
