Abstract

A physical conceptual model for liquid retention in fractured hard rocks is presented. A fractal model for unsaturated seepage in fractured rock masses of function among capillary pressure, effective water saturation and relative hydraulic conductivity is established. The comparison results of proposed model and the Brook-Corey model indicate that the proposed model seems to be adequate to describe the fractured rocks for small ranges of fracture aperture and the relative conductivity is mainly influenced by the maximum fracture aperture. The proposed model presents a very good description of water and air permeabilities over several orders of magnitude for the whole range of water saturation.
