摘要:
基于图形图像学与分形几何交叉学科理论，提出了一种用于描述节理面形貌的新方法—YUV维数法，该方法可替代传统分形维数且有其优势。在此基础上，通过对含两条粗糙平行节理岩石的SHPB试验，探讨了两条节理面形貌（以YUV维数描述）对应力波能耗的影响规律。研究结果表明：YUV维数法是一种新型表面描述方法，相对传统自相似图像维数有其优势；当两条节理YUV维数或节理YUV维数之和增大时，节理能耗值随之增加。出现上述现象的机理是：当节理面YUV维数增大时，岩石节理刚度相应减小，导致应力波穿越节理的能力降低，造成应力波能量耗散值增大。另外，能耗与YUV维数间呈现一种非线性关系，这种非线性关系是由节理的非线性变形所引发。为了工程应用之目的，同时给出了能耗与两条节理YUV维数间的二元函数关系。
Abstract:
Based on the interdisciplinary theory in iconography and graphics and fractal geometry, a new method used to describe the joints surface morphology was proposed, named as YUV dimension method, which can substitute for traditional fractal dimension with its advantage. On this basis, the influence laws of two joints surface morphology (described by YUV dimension) on energy dissipation of stress wave were investigated through SHPB test on rock with two rough parallel joints. The results showed that YUV dimension method is a new surface description method, and it has own advantage compared with traditional self-similar image dimension. With the increase of two joints YUV dimensions or their sum, the energy dissipation of joints grows up. The mechanism of this phenomenon is that with the increase of joints surface YUV dimension, the stiffness of rock joints decreases accordingly, which leads to the reduction in ability of stress wave to cross the joints and the rising in energy dissipation of stress wave. A non-linear relationship presents between energy dissipation and YUV dimension, which is caused by the nonlinear deformation of joints. The binary function relationship between energy dissipation and YUV dimensions of two joints was also proposed for engineering application.
