Resumo
The use of non-destructive methods for investigations of the physical stability conditions of dams has become increasingly important, mainly comparing geophysical and geotechnical methods of subsurface research. This association allows understanding and evaluating processes that compromise the physical stability of the dam, such as possible internal erosion (piping), for example. The recent disruption of mining tailings dams in Brazil generated an alert. The geophysical methods proved to be a research tool that can be worked in association with the classical geotechnical methods of dam instrumentation, assisting mainly in the maintenance, inspection and safety control of the structure, because of this the project becomes so important.
