摘要
以平行布置为例,用物理模型试验的方法研究了浮箱式防波堤在大潮差条件下的运动响应特性和透射系数的规律。结果表明:相同相对宽度下透射系数的数值在高潮位时与其它两个潮位有较大的差别,综合考虑运动响应和透射系数,对浮式防波堤的相对宽度设计给出建议。另外,通过对比不同锚泊系统布置形式的浮式防波堤在相同波况下运动和透射系数的大小,指出平行布置较适合大潮差海域,为工程实践提供参考借鉴。
Taking the parallel arrangement for example, we study the motion responses and transmission coefficients of pontoon-type floating breakwater under large tidal ranges by laboratory model tests. The results show that the value of transmission coefficients with relative width for the high tide is different from the other tide levels. By a comprehensive consideration of motion responses and transmission coefficients, we give suggestions on the relative width design of floating breakwater. In addition, based on the comparison study on motion responses and transmission coefficients under the same wave conditions of floating breakwaters with different mooring configurations, we point out that the parallel arrangement is more suitable for the water with large tide ranges. The research result may serve as reference for the engineering practice.
