摘　　要：基于计算流体动力学(CFD)与计算固体力学(CSM)的分区双向耦合模拟方法,发展了波浪与柔性水平板防波堤相互作用的耦合分析模型,采用文献中的试验数据验证流固耦合模型的合理性,利用数值算例分析柔性水平板防波堤的水动力特性。研究表明:柔性水平板防波堤和刚性水平板防波堤的反射系数均随着相对板宽(B/L=0.26~0.62)的增加先增大后减小,透射系数则反之;柔性水平板防波堤的掩护性能随着弹性模量(E=20~100 MPa)的降低先增强后减弱,通过选取合理的设计参数,柔性水平板防波堤相较于刚性水平板防波堤具有更好的掩护性能;在文中计算条件下,当E=80 MPa时柔性水平板防波堤达到最佳的掩护性能。Based on two-way coupled CFD-CSM method,this paper developed a coupled analysis model for the interaction between wave and flexible horizontal plate breakwaters(FHPB)which is verified by the physical model in the literature and researched the hydrodynamic characteristic of FHPB.The research shows that as the increase of the wave period,the reflection coefficient of the rigid horizontal plate breakwater(RHPB)and the FHPB first increases and then decreases while the transmission coefficient first decreases and then increases.The shielding performance of the FHPB increases first and then decreases with the decrease of elastic modulus,and the FHPB has better shielding performance than the RHPB by selecting reasonable design parameters.In this paper,the material which E=80 MPa has the best shielding performance.
