【 摘 要 】

Ten Barton's standard roughness rating profile curves have been digitized by the interpolation approach with MATLAB software. It is proved that the way of digitizing the JRC curves is feasible, based on the contrastive analysis of slope root-mean-square of the JRC curves provided in this article and the others. Considering both asperity inclination angle and amplitude, a new parameter, degree of impedance, has been proposed to determine morphology characteristics of joint. On the other hand, the degree of impedance can be further corrected with considering the elongation rate and equivalent depth, and the degree of impedance for joint with different sampling intervals has been calculated, which shows that the degree of impedance can better reflect the size effect of joint.
