Sobre la relación entre las distribuciones de los tamaños de poros y partículas del suelo

Alvaro Alberto López Lambraño, C. Fuentes, A. López Ramos

Abstract


The particle and void sizes distributions of the soil are related with the assumption that a void
constant relationship at all di§erent scales and a relationship between pore and particle size of
a given packing. In the relationship between pore and particle sizes, a particle elongation factor
is applied based on the Arya and Paris model. A áow trajectory tortuosity factor based on the
Fuentes model can also be applied. Since the void size distribution is associated to the soil water
retention curve, the proposed relationship can be used to estimate this curve from particle size
distribution.

Keywords


Areal porosity, volumetric porosity, fractal area-volume relationship, tortuosity factor, joint probability.
