摘要
随着近年海上风电的快速发展,海上风电基础的防冲刷问题越来越引起重视。为深入分析海上风电单桩基础的冲刷过程及防冲刷措施的效果,利用FLOW-3D三维模拟软件对有无防护下的单桩基础进行数值模拟并和模型实验对比。结果表明:FLOW-3D可以较好地反映各防护措施下的冲刷过程,与模型实验结果吻合良好;抛石和软体排在一定条件下可以有效防护海床冲刷。研究可为海上风电基础的冲刷计算和防护设计提供参考。
With the rapid development of offshore wind power in recent years,the scour prevention of offshore wind turbine foundation is more and more important.In order to deeply analyze the scouring process of monopile foundation of offshore wind turbine and the erosion prevention measures,FLOW-3D simulation software was used to simulate the monopile foundation with or without protection,and the results were compared with the experiments.The results show that FLOW-3D can reflect the erosion process under various protection measures,which is in good agreement with the model test results;riprap and soft mattress can effectively protect the seabed erosion under certain conditions.It can provide an important reference for scour calculation and protection design of offshore wind turbine foundation.
