| Sumario: | Rock massifs that constitute the Sierra Chica mountains have been matter of geotechnical studies for the execution of important rock road works that Cordoba Province has carried out in the last ten years. The stability analysis implemented for the construction of rocky slopes in mountain road works are performed using geotechnical models based on limit equilibrium theories and in the determination of safety factors, values that quantify the difference between real slope conditions and landslide conditions. These methods require a correct massif characterization, i.e., a geological model that properly represents materials and processes involve in the slope stability. With the objective of knowing mechanisms, models and instabilities geometry on the route RP34 inside the Sierra Chica mountains and for knowing the mechanical behavior of the materials, in the present study a back analysis was carried out on the western slope of the mountain range and on one of the slopes built on RP34. The analysis of the western slope was carried out in a sector where a slope generated for the construction of the route failed (EG15) and with the results obtained, a new slope of the route was analyzed (EG17) where landslides occur in the last year. This last analysis was carried out, through a global evaluation considering the possibility of a circular fault involving the entire slope and, in the sectors where the landslides occurred, local conditions were evaluated through a wedge failure analysis. |
