In the Beginning… There is the Earth
Characteristics of the structure: A farm of 26 wind-generators installed along the A10 motorway in the département of Eure-et-Loir, each 96 m high and with a power of 2 MW.
Our mission : The main difficulty in the geotechnical study (G12, G2, and G4 missions) concerns the potential presence of karstic voids in the Beauce limestones and marls.
We employed 5–9 soundings 25 m deep at the position of each wind-generator, systematically performing pressiometric tests in areas where anomalies were identified in the bore-hole parameter recordings. No voids were detected. We were able to adopt surface foundations for all 26 wind-generators.
