Resumen
En el presente trabajo se realizó una revisión de la bibliografía referente al cálculo de asentamientos y se determinaron los métodos analíticos y numéricos a emplear. Se muestran las principales características del software GeoStudio 2007, empleado para la modelación tenso-deformacional de presas de tierra. Se determinaron las generalidades para obtención del modelo numérico que caracterice el estado tenso-deformacional de una presa de tierra. Se efectuó la calibración matemática para la obtención del modelo numérico, y se realizaron los cálculos por los métodos analíticos y numéricos para el caso de la presa Abreus, comparándose los resultados con las mediciones del sistema de control técnico. Se llegó a conclusiones sobre los resultados obtenidos de los cuales se propusieron recomendaciones a tener en cuenta para el estudio y monitoreo de una presa.
In the present work a review of the bibliography regarding the calculation of settlements was made and the analytical and numerical methods to be used were determined. The main features of the software GeoStudio 2007, used for the tenso-deformation modeling of earth dams are shown. The generalities were determined to obtain the numerical model that characterizes the tenso-deformational state of an earth dam. The mathematical calibration was performed to obtain the numerical model, and the calculations were performed by analytical and numerical methods for the Abreus dam case, comparing the results with the measurements of the technical control system. We reached conclusions about the results obtained from which recommendations were proposed to be taken into account for the study and monitoring of a dam.
