Dataset for estimating wave transimission coefficients

This dataset is used for estimating stress wave transimission coefficient at rock joints directly from surface morphological parameters. Tten parameters related to surface roughness are selected, including three 2D and seven 3D parameters. For three 2D parameters, Z_2 is the root mean square of the first deviation of the profile, SF is the structure function of the profile, and i_a is the average inclination angle. For seven 3D parameters, S_z is the peak height of the joint surface, R_s is the ratio of the true area of the joint surface to the projected area, S_k is the surface skewness, S_s is the surface kurtosis, S_a is the arithmetic height of the joint surface, S_p is the maximum surface peak, and S_m is the maximum surface depth.
