APPLICATIONS
Dams and dikes are structures built with the purpose of creating reservoirs for the accumulation of water or mining waste, with varying sizes, from small earth masses to large concrete structures. These structures must have an adequate and efficient monitoring system in order to promote their operational safety. Good dam management is fundamental and must provide safe, stable and economical storage of water or waste, presenting minimal public health risks and acceptable social and environmental impacts during construction, operation and post-operation.
The DAS and DTS technologies developed by Immer Messen offer distributed deformation monitoring capabilities for the analysis of structural health (Structural Health Monitoring - SHM) of dams, monitoring of seismic waves and monitoring of thermal variations, constituting extremely useful tools for the identification, quantization and location of infiltrations, erosions and landslides.
Active and passive seismic interferometry techniques are used with the aid of data acquired with DAS equipment to measure seismic waves to characterize large masses, being able to identify and locate variations in density, compressibility and shear modules, which are the result of changes geophysics such as:
Monitoring of steam transport pipelines in refineries
Leaks in long-distance pipelines
