| Sumario: | In this project it is proposed the use of advanced numerical analysis for the study of mechanical slope instability and landslides in the Andes mountain range in Mendoza. Geomechanic modeling is a powerful tool for the evaluation of already-occurred landslides, rockfall and other phenomena, as well as for the prevision of characteristics and impact of future events. The phenomena of slope instability and landslides in natural soil and rock slopes are failure mechanisms caused by the different triggers with the consequent mobilization of small-to-enormous volumes of material - soil and/or rock by gravitational action. These phenomena can be grouped into two major phenomenological families: Instability of rock slopes and several mass-removal processes indicated here are landslides. They are induced by climatic phenomena, that is, the thermal amplitude in dry periods, and torrential rainfall, as well as due to seismic events, erosion of rivers and geomorphological factors. These problems often occur in the province of Mendoza. The events affect comunication and international trade activities of the international route N ° 7, main corridor that connects with Chile Republic and the Pacific ports. Also it is possible to mention the zone around the Potrerillos dam or mountain ways in Villavicencio area. Numerous field studies have been carried out to map the events that have occurred up to the present, as well as the regions with potential for instability. The geomechanical modeling of this kind of problem by the application of numerical tools is an important complement in research. It allows to evaluate, reproduce and predict the processes of instability, mechanics and kinematics through material models, dynamic calculation, detail of morphology and other geometric characteristics. However, research development using geomechanical modeling is now less developed. To contribute to the expansion of this research line, the present project is proposed. This project has been presented by researchers belonging to the Geotechnical Area of the IMERIS Institute (Ingeniería-UNCuyo), which carries out theoretical, field, physical laboratory and computational laboratory research lines. |
