【摘要】 运用AQWA软件,针对双浮箱-双水平板浮式防波堤,建立不规则波作用下浮体锚链的耦合模型,研究时域情况下,改变水平板与浮箱的垂直间距,分析浮体运动响应以及锚链受力情况;并深入探讨了不同波浪周期和波高情况下水平板长度对浮体运动响应以及锚链受力的影响。结果表明,增加水平板与浮箱的垂直间距和水平板长度,可以有效减小浮体运动响应和锚链受力。波高和波浪周期是浮体重要的水动力因素,波高越大,波浪周期越长,浮体运动响应越剧烈;当浮体水平板长度达到21米左右时,整个防波堤达到最佳锚泊状态。更多还原

【Abstract】 The numerical simulation model of twin-pontoon-plate floating breakwater is established by hydrodynamics simulation software AQWA.In the case of time domain,,the dynamic response and the mooring chain force are analyzed by changing the vertical spacing between the twin horizontal plate and the pontoon.The effects of the length of the horizontal plate on the motion response and the mooring chain force under different wave heights and periods are discussed deeply.The results show that the longer vertical spacing and horizontal plate are,the smaller response amplitude and mooring chain force are.And the wave height and period are important factors of water power floating body,the higher wave height is,the longer wave period is,the smaller response amplitude is.When the horizontal plate length is about 21 meters,the whole breakwater reaches optimal anchoring state.更多还原
