海上风机基础试验加载系统设计与建造

The Design and Construction of Offshore Wind Turbine Foundation Test Loading System

发展海上风电是我国“陆海统筹发展战略”的重要组成部分,也是实现“双碳”目标的重要举措。模型试验法利用模型与原型通过缩尺进行相似模拟试验,可定量和定性研究风机基础的承载性能,是一种常用的研究方法。文章介绍了一套考虑海上复杂环境致使基础受到复杂-复合荷载作用的模型试验加载系统,通过设置不同风荷载、波浪荷载、洋流荷载参数,实现多向、多种海洋环境荷载的长期-反复作用,能很好地模拟海上风机基础受荷。

The development of offshore wind power is an important part of China's"land and sea coordinated development strategy"and an important measure to achieve the"dual carbon"goal.The model test method uses the model and the prototype to carry out similar simulation tests through scaling,which can quantitatively and qualitatively study the bearing performance of the wind turbine foundation,and is a common research method.A set of model test loading system considering the complex-composite load on the foundation caused by the complex marine environment is introduced.By setting different wind load,wave load and ocean current load parameters,the long-term and repeated action of multi-directional and various marine environmental loads can be realized,which can well simulate the load of offshore wind turbine foundation.
