摘    要:提出了新的投影覆盖法———ProjectiveCoveringMethod(PCM),并结合无接触激光表面测量技术直接测定出断裂表面分维值D∈[2,3).建立了表面粗糙性投影覆盖概率函数,分析了节理(断裂)表面的多重分形性质.

关 键 词:投影覆盖法  岩石节理  断裂表面  多重分形

Abstract:Following fractal geometry introduced by B.B. Mandelbrot,many researchers have described quantitatively the roughness of fractured surfaces and also tried to establish the relationship between the fractal dimension and mechanical parameters. Extensive experiments and measurement show that, to some extent, fracture surfaces in rocks exhibit statistical fractal behavior in a certain range of scale. In fact, understanding of fractal behavior of fracture surfaces advances step by step. Initially, people paid at...
Keywords:projective covering method  fracture surface  fractal dimension of fracture surface  multifractal
