ESTIMATION ON VARIETY OF MACROSCOPIC DEFORMATION CHARACTER OF INTERMITTENT JOINTED ROCKMASS BY FRACTAL FEATURE
【摘要】 岩体结构的复杂多变是造成节理岩体宏观力学特性差异性的重要原因。应用分形几何学中的分维数作为描述岩体结构的定量指标,建立了分维数与岩体变形参数的相关模型,进而系统研究了某重大水电工程大型地下厂房不同工程部位的围岩变形特征。
【Abstract】 The complexity and variety of rockmass structure are the very important reasons to induce variety of macroscopic deformation character of jointed rockmass. To evaluate the variety of rockmass structure,a correlation model is set up between deformation parameters and fractal dimension. The dimension is made as a measureable guideline to describe the rockmass structure in this model. Based on this model,the deformation character of surrounding rockmass is studied for a large-scale hydroelectric underground powerhouse.
