The Fractal Properties of Scale Effect on the Density of Rock-Fill Materials

Abstract:

to study scale effect on the density of rock-fill materials, the relative density tests were carried out by physical tests and numerical tests. Fractal geometry theory was drawn into the gradation of rock-fill materials. Then, the fractal properties of scale effect on the density were investigated. There are close relations between fractal dimension D and densities of rock-fill materials. The densities are maximal when D is the critical value Dc. Furthermore, Dc is independent of the relative density Dr and the maximal diameter dmax. Truncation error is one of the main factors of scale effect of densities of rock-fill materials. The achievements in the paper lay a good foundation for further studying scale effect of rock-fill materials with fractal geometry theory.
