摘　　要：尾矿坝内部结构对其力学性质、变形特征和稳定性评价具有重要的影响.应用先进的分形几何学描述尾矿坝内部的结构特征,检验尾矿坝内部结构的分形性质,分析尾矿坝内部结构分形性质对尾矿坝力学性能的影响.研究表明,金矿尾矿坝坝体材料的粒径分布具有分形结构特征,粒径分布的分维值在一定程度上揭示了坝体材料在力学性能、渗透性能方面的性质.The internal structure of the tailings dam has an important influence on its mechanical properties,deformation characteristics and stability evaluation.In this paper,an advanced method,fractal geometry is used to describe the internal structure,inspect the fractal property of the internal structure and analyze the influence of fractal property on its mechanical properties of the tailings dam.Studies have shown that the distribution of the gold mine tailings dam material particle size has the characteristics of fractal structure,and to some extent,the fractal dimension of particle size reveals the characteristics of the mechanical properties and the nature of penetration of dam materials.
