Determining the surface roughness coefficient by 3D Scanner
Geologija, 2010 Currently, several test methods can be used in the laboratory to determine the roughness of rock joint surfaces.However, true roughness can be distorted and underestimated by the differences in the sampling interval of themeasurement methods. Thus, these
