| 摘 要： | 利用特征函数法对矩形浮箱式防浪堤的消浪性能进行分析。建立了浮堤与波浪相互作用的数学模型，求解各部分流域速度势。根据速度势及浮堤的横摇、纵荡、垂荡运动对波浪的绕、辐射影响，分析了浮堤的水动力特性，确定浮堤的消浪性能。计算结果表明，这种方法能对浮堤消浪特性进行较好的预测，可为模型试验或工程设计提供技术借鉴。

| Abstract: | Wave attenuation properties of rectangular pontoon breakwater were analyzed with eigen-function expansion.Mathematical model of wave interaction with floating breakwater was built and velocity potentials are calculated.The hydrodynamic properties and wave attenuation properties were analyzed,considering the breakwater motions influence to wave diffraction and wave radiation in roll,surge and heave.The calculation results demonstrate that this approach is a better method to forecast wave attenuation properties of floating breakwater.It offers technological reference for model test or actual project design. |
