Análise de estabilidade estrutural da barragem localizada no Rio Gigante

Abstract

Hydropower generation, a clean and renewable energy source, accounts for the largest percentage of our energy matrix. However, over the years, it has been realized that large dam constructions can have significant environmental impacts. This realization has shifted the focus from large hydroelectric plants to medium and small-scale hydroelectric generators. The primary structure ensuring the reservoir's functionality and enhancing the regular operation of the hydroelectric generator is the dam, which can be built with various characteristics. Therefore, the objective is to conduct an analysis of the structural stability of the dam located on the Gigante River, between the municipalities of Honório Cerpa and Coronel Vivida, ensuring the safety of the wildlife, flora, and population directly affected by the reservoir. Loads in action were determined and computed based on the literature, dimensions established in the field, and defined parameters of the dam. Information regarding different load combinations, water level heights, and dam dimensions were considered. Consequently, it was determined whether the dam is suitable for the potential repowering of the power plant previously located at the site.
