Analysis of Temperature Control and Crack Prevention Measures for Wind Turbine Steel–Concrete Hybrid Tower Foundations in Winter Construction
摘要
With the continuous expansion of wind power installations, wind turbinesWind turbine employing concreteConcrete-steelSteel hybrid tower structures have become increasingly prevalent. The foundation components of these structures face complex temperature controlTemperature control and crack prevention challenges due to their unique construction characteristics. This study, based on an onshore wind power project in Keshiketeng Banner, Inner Mongolia, utilizes the finite element software ANSYS to simulate and analyze thermal stresses in wind turbineWind turbine foundation concreteConcrete during winter constructionWinter construction, proposing effective temperature controlTemperature control and crack prevention solutions. As the project did not employ cooling pipe measures, temperature controlTemperature control and crack prevention primarily relied on surface insulation and reduction of concreteConcrete hydration heat. The final computational results demonstrate that by optimizing the concreteConcrete mix proportion to reduce the adiabatic temperature rise below 40 °C and applying approximately 1 cm thick polystyrene insulation, temperature-induced cracking can be effectively prevented.
