【摘要】 通过物理模型试验探究了规则波与"十"形防波堤的相互作用.试验时,将两块刚性薄板垂直拼接,固定于波浪水槽中,改变模型浸入水面以下深度、水波波陡、波长等参数进行系列试验.采用浪高仪测量模型前后波形,通过频域分析法处理数据得到相应波况下的透射系数,并与T形防波堤模型相比较.结果表明,堤后透射系数随波陡的增加而减小,随水平板相对板宽的增加而减小,随相对浸深的增加,先下降后上升,在相对浸深d/h=0.1时有最小透射系数.与T形模型相比,"十"形防波堤的消浪性能更优.更多还原

【Abstract】 The interaction between the regular wave and 十-type breakwater is explored through physical model experiment.Two rigid sheets were spliced vertically and fixed in the wave flume to simulate 十-type breakwater.A series of experiments were carried out by changing the depth of model immerged in water,wave steepness and wave length.The waveforms before and after the model were measured by wave gauges.And the transmission coefficients of corresponding wave conditions were obtained by frequency domain analysis method.The results were compared with T type breakwater model.The results show that the transmission coefficient decreases with the increased of wave steepness and relative plate width.The transmission coefficient decreases first and then increases with the increased relative submergence and it has a minimum transmission coefficient at d/h=0.1.Compared with the T-type breakwater,十-type breakwater has a better wave attenuation performance.更多还原
