Annotation: The experience of the design of foundations for wind power installations (wind turbines), which belong to a class of unique high-rise building height H=100…120 m and are characterized by high demands on their rigidity and stability, are presented. The problems of foundation design for wind turbine manufacturers «Furlender», «Vestas», «General Electric» capacity of 2.5…3.0 MW, which was first used in the wind power plants in Ukraine and have no analogues in the CIS, are reviewed. The article presents the basic types of calculations for the foundations of wind turbines, arranged in the compressible and incompressible grounds. We describe a step by step method of performing calculations bases and elements of foundations of wind turbines, as well as the need to set quantitative assessment and consideration of the effect of inhomogeneous structures in terms of temperature and shrinkage deformation of concrete in the foundations of the state of stress in the process of hardening concrete. The results of calculations of deformations of raft foundation for wind turbines various types and calculation of fatigue strength of anchoring elements of foundations are presented. A comparative analysis of the most appropriate calculation of finite element models of objects are made. Applied technology foundation design considered types of wind turbines based on the combination of traditional engineering regulatory calculation methods with computer technology structural design. It applied for the first time in the CIS and provides a reasonable design solutions and technical and economic indicators of the main structures. Considerations hardening and curing concrete in the technology adopted concrete foundation raft foundation accompanied by significant heat generation, it will limit the adverse effects of temperature and shrinkage deformation of concrete on the stress state of the massive foundation slabs.
Keywords: foundations of wind turbines, deformation, strength, fatigue calculations, finite element model, the characteristics of the stress-strain state.
