Segurança em barragens com mais de 50 anos no Estado de Santa Catarina

Abstract

The dams built more than 50 years ago, with the purpose of storing water for power generation in the state of Santa Catarina, were executed within a less rigorous context in terms of standards and guidelines. Knowing that currently, not all met the stability criteria of Eletrobrás, which requires meeting the safety factors for global stability, under loading conditions for Recurrence Time (TR) of 1000 years, and it was still necessary to meet the National Dam Safety Policy, which arose after approval of Law No. 12,334, of September 20, 2010, entrepreneurs needed guidance to verify that the structures that make up the bus shacks in their power plants were meeting the new guidelines. With the purpose of guiding entrepreneurs, a procedure was developed for safety assessment in structures with more than 50 years in the state of Santa Catarina. The procedure was successfully applied at the Celso Ramos SHP, belonging to Celesc Geração.
