2 Overview Motivation Components of dams and dikes structural health monitoring systems Distributed optical fiber sensors - Brillouin system - POF-OTDR Experimental validation of sensor systems Conclusion
3 Motivation Technical safety of geotechnical and civil infrastructure Nachterstedt, Germany, 18 July 2009 Cologne, Germany, 3 March 2009
4 Motivation Some important causes of dam and dike failures: Overtopping Settlement Tilting Piping Break of the inner slope Gliding Source: Franzius Institute, University of Hannover Critical zone: Landside of the dike Monitoring task: Spatially resolved strain and temperature detection
5 Components of dams and dikes structural health monitoring systems Break of slope, erosion, settlement Measurement device Geotextiles Strain distribution along sensor fiber Distributed sensor (silica optical fiber) Measuring signal Measuring section
6 Components of dams and dikes structural health monitoring systems Geosynthetics are used to strengthen riverbanks and for reinforcement of road and railway embankments. Intelligent geosynthetics: New trend: Adaptation of geotextiles and geogrids to the monitoring of ground construction! The geomaterials do not lose their original functionality by integrating sensors.
7 Components of dams and dikes structural health monitoring systems Silica and plastic optical fibers: Propagation of light followed by the phenomenon of total internal reflection at the border of the fiber's core and cladding. mechanical deformation, temperature changes Fiber optic sensors can be used to measure: in inaccessible areas in harsh environments distributed along several kilometers long sections.
8 Components of dams and dikes structural health monitoring systems Integration of fiber optic sensors Heavy machinery used for dike construction might damage the optical fibers. Manual embedding provides good results for the condition of the embedded sensors.
9 Components of dams and dikes structural health monitoring systems A long chain of transmission of physical quantities is to take into account: ground soil Geotextiles Coating and cable Optical Fibers Measuremen tdevice Earthmoving Deformation Strain Brillouin shift Each of the four parameters (distance range, spatial resolution, measuring accuracy, testing time) can be optimized at the expense of the other three!
10 Distributed optical fiber sensors Stimulated Brillouin Scattering (SBS) Brillouin scattering Laser signal f B Frequency Laser signal Brillouin scattering Characteristic frequency shift: f B ~ v A ~ T, ε
11 Distributed optical fiber sensors Brillouin system Sinusoidal amplitude modulation BOFDA Pump laser Light pulses EOM BOTDA BOTDA Measuring of the impulse answer BOFDA Measuring of the complex transfer function FUT Stokes laser Distance range: 20 km Spatial resolution: 0.5 m
12 Distributed optical fiber sensors Pulse POF-OTDR Fresnel reflection Rayleigh scattering POF-OTDR Luciol" Distance range : Spatial resolution : 100 m 10 cm Measuring range of strain : > 40 %
13 Experimental validation of sensor systems POF-OTDR Field test
14 Experimental validation of sensor systems d f B = 500 MHz/% at λ=1.55 µm d ε d f B d T = 1.1 MHz/K at λ=1.55 µm
15 Experimental validation of sensor systems Field test of distributed strain measurement Several samples of sensor-based geosynthetics have been embedded into a 15 m long laboratory dike at the University of Hannover.
16 Experimental validation of sensor systems Brillouin gain spectra
17 Experimental validation of sensor systems Strain distribution alongside the dike Strain value: bar 3 bar Strain [µε] Z [m]
18 Conclusion Methods for the distributed strain measurement in optical silica and polymer fibers have been implemented for the application in the field All components of the dike monitoring system were analyzed A precise specification of the system parameters will be possible after further field tests
