Abstract

The internal cavity of the foundation of steel-concrete composite wind turbine tower is designed to facilitate the prestressed construction. The load bearing mechanisms of this foundation are different from those of ring type and anchor type foundations commonly used in steel wind turbine towers. Based on a real project, an integrated model of prestressed tower-foundation-ground was built by using the finite element software Abaqus. The internal force and damage of the foundation of steel-concrete wind turbine tower under extreme load conditions were studied by using static loading method. Under extreme load conditions, prestressed reinforcement have little impact on the local pressure at the anchor end of the foundation. Pre-stressing the reinforcement effectively prevents concrete cracking and tower deformation. For areas experiencing extreme loads on both sides, simplified calculations for stress and reinforcement can be performed using the calculation formula of bracket.

钢-混凝土风力发电塔基础内力及损伤分析

钢-混凝土组合风塔基础内腔设计便于预应力施工。该基础的承载机制不同于钢结构风力发电塔常用的环式和锚固式基础。结合工程实例，利用有限元软件Abaqus建立了预应力塔-基础-地基的综合模型。采用静载法研究了极端荷载条件下钢-混凝土风力发电塔基础的内力和损伤。在极端荷载条件下，预应力加固对基础锚端局部压力影响较小。预应力钢筋有效防止混凝土开裂和塔体变形。对于两侧承受极端荷载的区域，可采用支架计算公式对应力和配筋进行简化计算。
