摘要

“防波堤+风电”作为海域立体利用的新模式，逐渐成为海上风电研究热点。为揭示防波堤-风机体系在风与地震联合作用下的动力响应特性，本文基于PLAXIS建立防波堤-风机一体化结构体系三维耦合数值模型，并以塔筒顶与防波堤顶水平位移作为量化指标，对比分析该结构体系在不同场地及荷载工况下的动力响应特性。结果表明：因塔筒和防波堤刚度差异，塔筒顶部位移显著大于堤顶位移；相较单一风荷载和单一地震荷载作用，风-地震联合作用会显著放大体系位移峰值，且该放大效应并非单纯的线性叠加关系；风-地震联合作用会改变防波堤-风机体系动力响应对场地土体性质的敏感性程度。因此，在实际工程设计中需综合考虑不同荷载的联合作用。本文结论可为“防波堤+风电”一体化工程的动力响应分析与设计提供参考与借鉴。

Abstract

The “breakwater + wind turbine” integrated utilization model has gradually become a focal point in offshore wind energy research. To explore the dynamic response characteristics of the breakwater-wind turbine system under the combined action of wind and seismic loads, this paper developed a three-dimensional coupled numerical model of the integrated breakwater-wind turbine structure by using PLAXIS. The horizontal displacements at the top of the tower and breakwater were used as the primary indicators to conduct a comparative analysis of the system’s dynamic response under various site and loading conditions. The results show that due to the difference in stiffness between the tower and the breakwater, the displacement at the top of the tower is significantly larger than that at the breakwater. Compared with the effects of wind load or seismic load alone, the combined wind-seismic loading significantly amplifies the system’s displacement peak, and this amplification is not simply a linear superposition. Furthermore, the wind-seismic interaction alters the sensitivity of the dynamic response of the breakwater-wind turbine system to the properties of the site soil. Therefore, in practical engineering design, the combined effect of different loads must be considered comprehensively. The conclusions of this paper can provide valuable references and guidance for the dynamic response analysis and design of “breakwater + wind turbine” integrated projects.
