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°.

压实砂土材料的强度各向异性

本文介绍了压实载荷引起的含“各向异性织物”的含沙样品强度各向异性的实验研究结果。介绍使用的直接剪切设备。为了制备各向异性样品，将压实至最佳含水量的样品冷冻。然后从样品中钻出六个具有不同剪切角的样品。钻孔后，将这些样品放入剪切箱中并加热至融化。对于剪切角为+ 15°的样品，观察到最大剪切强度。
