Monitoreo geodésico mediante técnicas GNSS en el estudio de movimientos de ladera. Caso de estudio Yanacocha

Abstract

Abstract: Landslides are a problem in areas with complex geological conditions, due to their impact on ground stability, as occurs in the Yanacocha sector, Loja province. Therefore, this study analyzes the behavior of the terrain using geodetic monitoring techniques, specifically through the use of GNSS systems. For the development of the research, a non-permanent network of control points was implemented distributed throughout the study area and observed with dual-frequency GNSS equipment in Fast Static mode. The information obtained is broken down into two measurement campaigns, processed, and compared, allowing the identification of ground displacements and the estimation of the annual movement velocity. The results show that the slope exhibits active and non-uniform behavior, with sectors that have greater magnitudes of displacement. The information generated constitutes a reliable technical contribution that can be used as a basis for geotechnical risk assessment, technical decision-making, and the definition of mitigation and monitoring measures appropriate to the terrain conditions.
