In this work, we have given an analogical method for estimating the fractal dimension three-dimensional fracture tortuosity (3D-FT). The comparison and error analysis of rigorous methods on 3D-FT were carried out in work. [Formula: see text] from proposed is function 3D average ([Formula: length text]. with high accuracy indicates good consistency embodiment physical meaning relatively convenient calculating premise ensuring accuracy.
