Seismic structure at the test site for wind energy research, WINSENT, Southwest Germany
Main Article Content
Abstract
The subsurface at the Wind Science and Engineering Test Site in Complex Terrain (WINSENT) in SW Germany is studied to derive its underground structure and 3‑D seismic velocity distribution. These parameters are important for further geotechnical studies to better understand the soil‑structure interaction of wind turbines and their underground. This knowledge is needed for the save
construction of modern wind turbines on land whose nacelles reach altitudes of more than 150 m above the ground. Another issue are ground motions which are emitted from wind turbines and can be measured up to distances of several kilometers. We describe the fieldwork at the wind energy test site and the seismic inversion models. The seismic velocities are low compared to other studies due to the weathering and karstification of the Jurassic limestone at the site. We derive 3‑D compressional and shear wave velocity models with minor lateral variation which can be used as input for numerical modelling of wave propagation to explore vibrating wind turbines and their emissions.
