Abstract: In order to explore the influence of the shapes of the shear box on the internal friction angle of grain in the case of keeping other variables the same, the author obtained the experiment results of the internal friction angle of grain under different shapes of the shear box by contrasting the self-designed square-circle shape shear box with the circle shape shear box in the direct shear test. After being analyzed and compared, the experiment results demonstrated that the internal friction angle of the grain was bigger under the condition of the square-circle shape shear box. So the shapes of the shear box had a certain influence on the test of the internal friction angle of grain.
