CASTRO CAICEDO, Álvaro de Jesús  and  PEREZ PEREZ, Diana Marcela. CORRELATIONS BETWEEN THE RMR AND Q GEOMECHANICAL CLASSIFICATIONS AT "LA LÍNEA" EXPLORATORY TUNNEL, COLOMBIAN CENTRAL ANDES. Bol. cienc. tierra [online]. 2013, n.34, pp.42-50. ISSN 0120-3630.

Correlations between the RMR and Q geomechanical classifications schemes obtained during underground geotechnical surveys at the 8.55 km length "La Linea Pilot Tunnel" (TPL) within the Central Andes of Colombia are presented. Correlations were defined based on geological and geotechnical evidences. The correlations were statistically assessed concluding that these proposals are acceptable. The proposed correlations are expected to be useful in the design and construction of the La Linea roadway tunnel.

Keywords : RMR Rock Mass Classification; Q Rock Mass Classification; La Línea Tunnel; Segundo Centenario Tunnel; Colombia.
