摘    要:将数字图像处理技术引入到岩石破裂过程分析RFPA2D(Rock Failure Process Analysis)系统,建立了岩石细观结构破坏过程分析方法.首先提取岩石的细观结构图像,再转化成RFPA2D的前处理数据和数值分析网格,然后进行应力求解和破坏分析.以花岗岩细观结构为例,阐述了运用基于数字图像处理技术的RFPA2D方法进行岩石细观结构破坏分析的过程.结果表明,在岩石破裂过程数值模拟分析中引入数字图像处理技术是岩石细观结构破坏力学行为研究的一种方便而有效的方法.

关 键 词:数字图像  细观结构  RFPA~(2D)  细观力学

Abstract:Digital image processing technique is introduced into Rock Failure Process Analysis code and a new micromechanical analysis method of rock failure is established. By extracting the information of microstructure of rock in meso-scale, image data are fed into RFPA analysis. This method enjoys the advantage of failure process analysis of RFPA2D. Using a granite rock as an example, this paper illustrates the process of micromechanical analysis of rock failure. The results show that the digital image processing based RFPA2D method is an effective method to study micromechanical behavior of rock in meso-scale.
Keywords:digital image  microstructure  RFPA2D  micromechanics
