Quantitative Description of Orthotropic Fabric of Sand
Abstract Based on the microscopic theory of sand fabric, the novel amplitude parameters describing the spatial arrangement of non-spherical particles is defined, and the verification with the microscopic test for Toyoura sand is conducted. The spatial arrangement of non-spherical sand particles in the orthogonal coordinate is described with two independent angles, one can define three expressions of amplitude parameters which can be quantitatively determined by image analysis on the orthotropic plane. Only two of the three magnitude parameters are independent, with which the three-dimensional orthotropic expression of fabric can be deduced. The expression is used to describe sand properties of orthotropic, transverse isotropic and isotropic. Experimental results show three amplitude parameters with a clear physical meaning can reflect the variation of orthotropic plane.
