摘　　要：应用分形几何理论,基于散体物料试验数据,对物料颗粒组成特征分维值、不同应力水平下的分维值变化及其对抗剪强度的影响进行了分析.结果表明,分形几何理论是联系物料微观与宏观力学性能的有力工具.Base on the experimental results, the fractal geometry is applied to analyze the following aspects, such as the fraetal dimension, the changes of the dimension under different level of stress and its relation to the strength of the shearing resistance. According to the relative analysis, it is proved that the fractal geometry is a bridge to combine the microcospic and macroscopic mechanics properties.
