    摘要:

    通过物理模型试验的方法,观测海冰与高桩承台式海上风电基础的相互作用进程,测定不同冰速和冰攻角下基础结构所受的冰力时程,并对结果进行分析与讨论。结果显示,靠船构件与冰排的先期作用致使冰排累积了一定程度和范围的损伤,有利于减小基础结构所受的冰力极值。该研究成果对高桩承台式海上风电基础结构在寒区海域的工程应用具有一定的借鉴意义。

    Abstract:

    Through the physical model test method, the interaction process between sea ice and high pile cap foundation of offshore wind power is observed, the ice duration of the foundation structure under different ice speeds and ice attack angles is measured, and the results are analyzed and discussed. The results show that the accumulation of certain degree and extent of damage of the ice raft is caused by the early action of the ship components and the ice sheet, which is contributed to reduce the ice force extreme value of the foundation structure. The research results are of certain reference significance for the engineering application of high pile cap foundation of offshore wind power in cold regions.
