Resumo

Roughness characterization and JRC estimation have been made on rock joints of the Monte Seco tunnel. The authors have adapted field profiling of discontinuity surfaces to be able to estimate JRC using 3D laser scanner images. Results indicate similarity between traditional and laser scanning methods. The data also confirms the JRC size effect and the importance of evaluating field scale roughness. . . .
