Análise comparativa de modelos de fichas de inspeção visual entre o Brasil e outros países: perspectiva da prevenção de acidentes em barragens

Abstract

An indisputable fact is that the dams have been deployed throughout Brazil as an alternative to meet the demands: energy, water supply and human supply existing in the basins and users (mainly, urban), and it is up to the inspection body to perform a regular inspection to evaluate the dams. Even though at the design, design and construction stage the controls are executed in an appropriate way, there will always be assigned uncertainties that must be controlled by monitoring the evaluation and performance of the structures. Mainly due to the heterogeneity and uncertainties of the parameters of the materials (foundation and construction). This work aims to perform a comparative and critical analysis of the models of regular visual inspection chips in Brazil, presenting the fundamental characteristics and concepts for the advancement of regular visual inspections in the prevention of dam accidents, considering the dam safety management adopted in Portugal. It is hoped that the comparisons and critiques of this work can contribute and provide subsidies for an improvement of the safety of the dam, aiming at an advance of the regular visual inspections in Brazil and, at the same time, collaborate with the safety management of dam related to the issues that will be addressed.
