摘要

近年来,为解决能源安全和气候变化问题,国际社会对绿色能源的需求不断增长。迄今为止,由于风能资源的高可用性,风能部门可能取得了最大的进步。然而,在海上安装风力涡轮机提出了新的重大工程挑战。这些能量转换器的海上基础必须能够抵抗大的倾覆力矩以及波浪和风引起的多次侧载荷循环。因此,需要一个高效、经济的基础来支持涡轮机变得越来越重要。本文考虑了海上风力发电机组重力基础系统的具体设计。基础是一个锥形空心混凝土重力型结构,它位于海底,利用其自重来支撑涡轮机。在爱尔兰布莱辛顿的都柏林大学测试场地,一个拟议地基的比例模型已经进行了实验测试。本文介绍了本研究的结果。

: In recent years, the international demand to produce green energy has been growing to address the issues of energy security and climate change. To date, the wind sector has probably advanced the most due to high availability of wind resources. Erecting wind turbines offshore, however, presents significant new engineering challenges. Offshore foundations for these energy converters must be able to resist large overturning moments as well as numerous cycles of lateral loading caused by wave and wind. Thus, the need for an efficient cost-effective foundation to support the turbines is becoming more important. In this paper, a specific design of a gravity base foundation system developed for offshore wind turbines is considered. The foundation is a conical hollow concrete gravity type structure which rests on the seabed and utilises its self-weight to support the turbine. A scale-model of the proposed foundation has been experimentally tested at the University College Dublin test site in Blessington, Ireland. This paper presents the findings of this research.
