Resumen
[ES] Este trabajo tiene como finalidad realizar un análisis del deslizamiento de la zona seleccionada, calculando su factor de seguridad, indicando en qué medida los parámetros de resistencia al corte pueden reducirse para llevar la ladera a un estado de equilibrio límite. Se aplicaron y combinaron diferentes métodos de campo: topografía a partir de posicionamiento GNSS, tomografía eléctrica, y el análisis del deslizamiento a través de la modelización en programas de ordenador. El proceso para llevar a cabo el análisis y lograr los objetivos planteados consistió en realizar un estudio preliminar de la zona, mediante descripción geológica, geotécnica y de clima entre otros, que al combinarlos con los resultados de los estudios de campo permitió generar un modelo matemático análogo a las condiciones. Tras el procesado con software específico se obtuvieron resultados del factor de seguridad y el círculo de deslizamiento crítico, los cuales se analizan a lo largo del contexto.
[EN] The aim of this study is to perform an analysis of the landslide of the selected area, calculating its safety factor, indicating to what extent the shear strength parameters can be reduced to bring the slope to a state of limit equilibrium. Different field methods were applied and combined: topography from GNSS positioning, electrical tomography, and slip analysis through modeling with computer programs. The process to carry out the analysis and achieve the proposed objectives consisted of a preliminary study of the area, through geological, geotechnical and climate description among others. This combined with the results of the field studies allowed to generate a mathematical model analogous to conditions. After processing with specific software, results of the safety factor and the critical slip circle were obtained, which are analyzed throughout this context.
