陆上风电装配式基础结构研究综述OA北大核心CSTPCD

The foundation of onshore wind turbine(OWT)structure is usually constructed by cast-in-situ concrete,which is inefficient,polluting,and difficult to guarantee quality,either not conducive to the high-quality development of the wind power industry.The prefabricated wind turbine foundation adopts the construction method of standardized design and factory production,which can significantly shorten the construction period of wind farms,effectively guarantee the quality of the foundation,and reduce the pollution to the environment.It is one of the important measures for the transformation and upgrading of wind power and reducing costs and increasing efficiency.This paper collects,sorts out and summarizes the research of prefabricated OWT foundation and its state-of-the-art research.According to the characteristics of the wind power prefabricated infrastructure,it lists six main types of wind power prefabricated infrastructure,such as raft foundation and multi-footing foundation,and makes a detailed analysis of the characteristics and research status of each type,and lists some onshore wind farm projects that apply prefabricated wind turbine foundation worldwide.The results show that the design basis of OWT prefabricated foundation structures needs to be further improved,the existing structure forms should be optimized,and further research on design methods and performance control should be promoted.
