Strength Anisotropy of Compacted Sandy Material

The paper presents the results of an experimental study of strength anisotropy in sandy samples with “anisotropic fabric” induced by compaction loading. A direct shear apparatus used is introduced. To prepare anisotropic samples, a specimen compacted to optimum water content was frozen. Six samples, each with a different shearing angle were then bored from the specimen. After boring, these samples were placed in a shear box and heated to melting. The maximum shear strength was observed for a sample with shearing angle +15°.
