Análisis de la estabilidad al deslizamiento profundo de las presas de hormigón a gravedad cimentadas en suelo, en los sistemas fluviales de derivación

Abstract

The ongoing degree work encompasses a gravity weir dam foundation to the ground, which starts with shear indicators of the foundation for clayey grounds and also for a different kind of weir dam heights, trying to obtain the least favorable scenario to perform the analysis of a deep-seated landslide. First, the hydraulic analysis was carried out for a different dam heights, starting at 5m, using different height and with reference bases of the shear for clayey grounds, We calculate and determinate the process of hydraulic conditions of the weir dam, which are to determine if it necessary to incorporate energy dissipation works, being necessary in the current study, We proceed to determine the sizing of a well and a dissipation slab. Since the current study is based on weir dam foundation to the ground, we proceed with the scheme of the triangular elementary profile, with the intended purpose to preserve the base of the triangular elementary profile. Subsequently the result of triangular elementary profile we determine the weir Creager profile to obtain its structure. When we obtain the transversal section of the weir dam, the acting forces and the combination which are going to be inflicted, we proceed to make both stability and resistance analysis. As result of the previous calculations, we proceed to extend the structure of the weir dam by carrying out three different schemes. As results of different schemes, heights of weir dams and forces combinations, performing the deep landslide sliding analysis, with the help of circular-cylindrical planes in which random points are taken and circular failure surface is plotted to obtain the lowest deep-seated landslide safety factor.
