摘要:

风能具有清洁、储量丰富且可再生的特点，发展风电技术是推进“碳中和、碳达峰”的重要举措。现基于某风电工程，运用有限元数值分析对中空式风电承台的抗弯承载力进行研究。对弯矩作用下中空式承台的内力分布特征进行分析，着重研究了承台配筋对结构抗弯承载力的影响，并针对性地提出了配筋优化方案，有效提高了中空式承台的极限抗弯承载力，为设计和施工提供一定的理论支撑。

Abstract:

Wind energy is clean, abundant and renewable. The development of wind power technology is an important measure to promote "carbon neutralization and carbon peak". The bending bearing capacity of the hollow wind power base slab is studied by the means of finite element numerical analysis based on a wind power project. The distribution characteristic of internal force of hollow base slab under the bending moment is analyzed. The effect of base slab reinforcing bars on the bending bearing capacity of the structure is specially studied, and the optimization scheme of reinforcing bars is put forward in order to effectively improve the extreme bending bearing capacity of hollow base slab, which provides some theoretical support for the design and construction.
