| 英文摘要 | This paper studies the effects of angularity and coarse particle content on the shear behaviour of granular mixtures via the discrete element method. The contributions of different contact types to the shear strength are quantified, which can be used to classify the structure of granular mixtures. After that, a microscopic analysis of the effect of angularity on the thresholds of the granular mixtures is presented. Finally, a method that can predict the critical friction angle of granular mixtures at arbitrary coarse particle contents is proposed. The validity of the prediction method is verified by comparisons with the experimental and numerical data in other studies. |
