Correcting the Permeability Evaluation of Elliptical Rock Fractures in Triaxial Shear-Flow Experiments Considering Channeling Flow

Highlights Thirty groups of aperture fields with different mean and standard deviation values were attained to investigated the effect of channeling flow on the permeability evaluation. The ratio of permeability of elliptical models to that of equivalent rectangular models is proved to be controlled by the salience of channeling flow. A corrected function was proposed to accurately calculate the permeability of elliptical fractures in the triaxial shear-flow experiments.
