2. Operating principles of wind turbine foundations
2.1 The normative design context
Standard NF EN 61 400 of June 2006 specifies the design requirements for onshore wind turbines. However, this standard provides little guidance on foundation design and dimensioning. For example, paragraph 11.8 entitled "Assessment of soil conditions" states that "soil properties at a proposed site shall be assessed by a professionally qualified geotechnical engineer, with reference to available local building regulations and standards".
Focusing on geotechnical aspects, the French standards and recommendations that will guide the design and construction of foundations for their geotechnical component are mainly :
