Optimised design of wind turbine gravity foundations
Abstract eng: South Africa has seen an exponential growth in the provision of wind energy and the construction of windfarms in recent years. A primary structural component of any wind farm is the foundation required to support the turbine structure. Traditional turbine foundations are normally massive gravity structures, circular in shape designed based on simplified methods, often based on the recommendations by the turbine suppliers. Using sophisticated 3-D soils and structural modelling it has been established that material savings of 30–40% can be achieved relative to the simplified design methods. Founding materials are modelled using 3-D PLAXIS based on material parameters obtained from the geotechnical investigation and the concrete foundation is analysed assuming full non-linear material behaviour using DIANA 3-D software where the reinforcement is modelled discretely, taking into account the benefits of stress redistribution at the ultimate limit state.
