This paper presents seismic measurements at a large hydroelectric power plant dam in the south of Brazil. The seismic measurements were realized using optical fibre distributed sensor system technology and aim at diagnosing possible structural problems inside of the dam. Studies carried out at a laboratory scale dam using geophones as well as optical fiber sensors are also presented. Results are very promising and indicate the potential of the technology using both active and passive seismic techniques to solve major monitoring problems that cannot be addressed by today’s technology.

摘要

This paper presents seismic measurements at a large hydroelectric power plant dam in the south of Brazil. The seismic measurements were realized using optical fibre distributed sensor system technology and aim at diagnosing possible structural problems inside of the dam. Studies carried out at a laboratory scale dam using geophones as well as optical fiber sensors are also presented. Results are very promising and indicate the potential of the technology using both active and passive seismic techniques to solve major monitoring problems that cannot be addressed by today’s technology.
