NON-DESTRUCTIVE METHODS IN CONSTRUCTING "CRISTO REDENTOR" TUNNEL
EL APORTE DE LOS METODOS NO DESTRUCTIVOS PARA EL ESTUDIO DE LOS MATERIALES ROCOSOS Y SU ESTADO DE DESCOMPRESION EN LA OBRA TUNEL INTERNACIONAL "CHRISTO REDENTOR"
Before starting construction on the international "Cristo Redentor" Tunnel, between Argentina and Chile in the Andes Mountains, the terrain was evaluated using mostly prospecting techniques that provided the necessary information at a minimum cost. Engineers determined the petrographic qualities, structural aspects, state of compression or alteration, and physical condition of the rock to determine the construction methods needed to build the tunnel, as well as the cost aspects and safety factors of the work. An identical analysis was carried out in the identification study of the material adjacent to the cut profile, to provide information on geometry of the strata and identify weak or broken areas. These field tests, coupled with geolectric and geoseismic measurments and laboratory tests, made possible pre-construction calculations in a speedy and reliable manner. (Author)
