| 中文摘要: |
| 基于线性势流理论,对斜向波与消浪室内带部分填料的开孔板式防波堤结构的相互作用进行了理论研究.利用匹配特征函数展开法给出了开孔防波堤结构反射系数和波浪力系数的理论计算方法,在极限情况下的计算结果与已有结果一致.利用数值算例分析了开孔结构反射系数和波浪力系数的主要影响因素.增加消浪室内填料厚度通常可以降低开孔墙结构的波浪力系数,加大结构的反射系数.随着波浪入射角度的增加,带填料防波堤结构的反射系数值先减小,达到最小值后又单调增加. |

| The interaction of diagonal waves with perforated wall breakwater partially filled with rock fill is studied using t he linear po tential theory.By means of the matched eigenfunction expansion method,an analy tical method is presented to calculate the reflection coefficient and the wave force coefficient of the breakwater.The calculated results of the reflection coefficient for limiting cases are the same to the existing results.The main influencing factors of the reflection coefficient and the wave force coefficient are analyzed by numerical examples.With the increasing of thickness of rock fill,the wave force coefficient on the perforated wall generally decreases,while the reflection coefficient increases.With the increasing of the in cident angle of the wave,the reflection coefficient of the breakwater first decreases,reaches its minimum,and then increases monotonously. |
