The fractal dimension of the pore‐volume inside soils

Abstract

Abstract This paper deals with the applicability of the theory of fractal geometry on the pore‐volume V. It describes the porous medium [soil] by characterizing the pore‐size distribution over a range of pore sizes through a single number, the fractal dimension D. D is calculated from the relation Vp ± P D‐3 , where P is the pressure of the water‐retention curve and Vp is the cumulated pore volume. The fractal dimension D for the different pore‐size distributions ranges from 2.1 to 2.8 and is an intrinsic measurement for the degree of space filling of the different pore systems.
