CAMACHO TAUTA, Javier Fernando et al. STRENGTH TO THE CUTTING IN DISCONTINUITIES WITH DIFFERENT DEGREES OF ROUGHNESS. Cienc. Ing. Neogranad. [online]. 2009, vol.19, n.1, pp.55-70. ISSN 0124-8170.

In this research triaxial testings were done on artificial rocks made with a mortar (cement, sand and water) of different strength. Cylinders were made with and without a discontinuity orientated to 60° with regard to the horizontal axis and three different degrees of roughness, (polished flat, polished wavy and wavy). The mortar testing strength parameters were obtained and was analyzed the influence of the different roughness degrees by the Barton's criterion, obtaining the roughness coefficient of the discontinuity.

Palavras-chave : JRC; roughness; discontinuity; triaxial in rocks.
