The tests<br>conducted in this research include 20 hollow cylinder torsion shear tests under torsional loading conducted on<br>Tehran sand with high angularity. The confining stresses of the samples were 100, 200 and 400 kPa, and the<br>effect of the inclination angle of the major principal stress to the vertical axes was also studied. In each confine<br>stress three inclination angle 15, 30 and 60 degrees were applied. According to the results, an increase in the<br>alpha will result in a more contractive behavior in the sands. The effect of anisotropy also becomes more obvious,<br>as the confining stresses increases; however, it was found that the mechanical properties of sands changed<br>markedly with confining stress. To explain the effect of particle shape on the mechanical behavior of sand, with<br>its increase the soil sample behaved in an isotropic manner and the shear strength of the sample decreases.</p> ER -
