岩石结构分形维数与岩石压缩强度关系的探讨

THE RELATIONSHIP BETWEEN FRACTAL DIMENSION OF ROCK TEXTURE AND COMPRESSIVE STRENGTH

摘要: 运用分形几何学的理论和方法研究煤层顶板岩石的结构,发现岩石的粒度结构和孔隙结构均具有自相似性,粒度分形维数和孔隙分形维数与岩石压缩强度之间有良好的相关关系,故可以用岩石结构的分形维数定量表述岩石的压缩强度。

Abstract: The fractal geometry theory and methods are used for studing rock texture of coal seam roof.The study shows that the rock grains structure and pore structure are self-similarity. And there are well correlative between fractal dimension of rock texture and compressive strength. It may be possible that fractal dimention of rock texture can express rock compressive strength.
