ROUGHNESS SCALE EFFECTS AND FRACTAL DIMENSION . PROCEEDINGS OF THE FIRST INTERNATIONAL WORKSHOP ON SCALE EFFECTS IN ROCK MASSES, LOEN, NORWAY, JUNE 7-8 1990

Using shadow profilometry, the authors have investigated the effect of the scale of observation on measurements of roughness, and have confirmed that a roughness scale effect exists. The method of measurement acts as a bandpass filter, allowing scale effects to be quantified from images at different magnifications. Fractal dimension has also been investigated as a means of characterizing roughness. The rock profiles tested were found not to be self-similar at different scales of observation, providing further evidence for a scale effect. (Author/TRRL)
