FRACTAL GEOMETRY STUDY ON STRUCTURE OF JOINTED ROCK MASS
节理岩体结构的分形几何研究

On the basis of statistical homogeneity of structure,the rock mass structure is studied by applying fractal geometry. Firstly,the 3D network modeling technique is used to establish the probability model for the randomly distributed discontinuities in the statistical homogeneity of structure. With the aid of computer,the structure of rock mass is regenerated on the screen. Secondly,2D and 3D specimens are extracted from the 3D network model of discontinuities,and finally the fractal dimensions of the specimens are computed. The results indicate that the 3D fractal dimension is equal to the 2D fractal dimension added by one. This means that,from 3D point of view,the structure of jointed rock mass has the property of self-similarity.
