| 摘 要： | 作为一种新型的深水海上基础型式,桶形基础在海上风机设施设计与建设中逐步得到了发展和应用。以三桶基础为例,采用大型有限元软件ABAQUS对海上风机多桶基础的承载特性进行了三维有限元数值分析。根据海上风机的荷载受力特点,分别探讨了三桶基础在竖向荷载、水平荷载和力矩作用下的极限承载力,得出荷载作用方向及桶间距对极限承载力的影响程度,研究成果为复合加载模式下海上风机多桶基础的承载特性分析奠定了基础。

| Abstract: | As a new type of deep-water offshore foundation,suctional bucket foundation has been gradually used in the design and construction of offshore wind turbines.However,the research results of previous work principally focus on the analysis of stability of single-bucket suctional foundation,and the behavior of bearing capacity and joint-work mechanism of multi-bucket suctional foundation have not been well understood,and need further studies to meet the increasing requirement of engineering practice.Based on th... |
