“Caracterización geomecánica de los macizos rocosos que conforman los taludes ubicados entre las abscisas 11+340 a 13+480 del sector Cachipamba – Taquil, parroquia Taquil, provincia de Loja”

The present project, entitled " Caracterización geomecánica de los macizos rocosos que conforman los taludes ubicados entre las abscisas 11+340 a 13+480 del sector Cachipamba Taquil, parroquia Taquil, provincia de Loja ", was based on an analysis of a 2140 m long section of the road. Initially, a topographic survey was carried out using an unmanned aerial vehicle, obtaining digital elevation models, surface models, and orthomosaics at a 1:1000 scale. Paleozoic, Paleocene, and Quaternary lithological units were identified through detailed geological mapping. Fourteen lithostructural zones with differentiated characteristics were defined. In the geomechanical campaign, the discontinuity families were differentiated, and their preferred orientations, spacings, persistence, and roughness, among other properties, were measured. Laboratory tests were carried out to determine physical-mechanical properties such as density and compressive strength. The rock mass was geomechanically classified using the RMR classification model, where it was evident that the rock masses in the study area are between II and IV classes, that is, from good to poor rock. In addition, the susceptibility to failure of the rock masses was analyzed by applying the Slope Mass Rating Continuous (SMR-C) methodology to determine the quality of the rock masses and their respective stability status in relation to planar and toppling failure types. Information from fourteen geomechanical zones was compiled, indicating rock masses of very poor to good quality, and for toppling failure, very poor to normal quality rock masses. In the calculation of SMR-C using GIS, it is concluded that the results will depend on the topography according to the investigation scale, the number of geomechanical stations surveyed, and the determination of the laboratory-resistant parameters. Finally, the results show that the area presents an irregular topography, with heterogeneous geological units and a variable geomechanical state from fair to poor. The susceptibility to failure maps allows the identification of the areas that require stabilization measures. Keywords: Slope Mass Rating, RMR, Geomechanics, Slope, Planar Failure, toppling failure.
