Abstract: A new fractal description method for three-dimensional roughness characteristics of rock joint is proposed and researched. Firstly, based on the scanning data of joint surface morphology, the joint surface is reproduced in the discrete form of triangular nets; and then the calculation method of 3D root mean square resistance angle is established. Secondly, fractal theory is applied to propose a new fractal description method to describe 3D roughness characteristics of rock joint on the basis of 3D root mean square resistance angle. Finally, the new method is used to characterize the roughness of natural basalt joint and tensile granite joint. Research results show that the new method can well reflect the 3D morphology of joint and it can also describe the anisotropy of roughness. Research results offer the foundation for further studying the shear strength and shear constitutive law of rock joints.

Key words: rock mechanics, joint, roughness, fractal, anisotropy
