摘要：The safety of a dam is the result of a series of factors, including structural, geotechnical, hydraulic, operational and environmental aspects.In Brazil, Law No.12.334 of September 2010 establishes the National Dam Safety Policy, which requires safety reports and monitoring inspections for existing dams.The inspection comprises a set of devices installed on the dam, which are used to assess the structural behavior based on performance parameters of the structure, such as displacements, flows, stresses, slopes and others.Dam auscultation procedures, historically, have been performed since the 1950s.Since then, there have been significant advances in instrumentation and dam auscultation methods.This work presents a theoretical approach on technical and scientific aspects of dams in Brazil, based on a state-of-the-art literature review, involving auscultation of dams in the context of design codes, concepts, instrumentation, safety, procedures and monitoring methods.
