Dimensionamento e análise de estabilidade de barragem de gravidade em concreto.

Abstract

The construction of dams has increased dramatically in our country, especially small and medium-sized dams of concrete-gravity type. There are several forms to calculate the dimensions for this dam type, most of which are of U.S. origin. This work was made a brief summary of the types of concrete dams, followed by the compilation of active loads and loading conditions proposed by the bibliography for gravity-type dams. It also addressed the equational methods for analysis of global and local dams stability, as well as features of their construction materials. A hypothetical profile dam was simulated by equations of desing and sizing and this profile was analysis, checking its safety against rupture, maximum stresses and strains, with the support of software based on the theory of finite elements. In the end, the results were analyzed and compared with the recommended bibliography, obtaining the conclusions of this study.
