摘　　要：为了提升水平板防波堤的消浪性能与透水性能,设计一种迎浪侧半开孔式水平板防波堤。在不同相对板宽、潜深及波高条件下,通过物理模型试验研究不开孔式与迎浪侧半开孔式两种水平板防波堤的透射系数Kt、反射系数Kr及耗能系数Kh,系统对比两种水平板防波堤的消浪性能。结果表明,在试验参数条件下,迎浪侧半开孔式水平板防波堤的透射系数整体上小于不开孔式水平板防波堤,且两种水平板防波堤的透射系数均在相对板宽为0.166或0.212时达到最小值;两种水平板防波堤反射系数的变化趋势相近,迎浪侧半开孔式水平板防波堤的反射系数整体偏小;迎浪侧半开孔式水平板防波堤的耗散系数整体大于不开孔式水平板防波堤,在相对板宽为0.166或0.212时达到最大值。迎浪侧半开孔式水平板防波堤的消浪性能优于不开孔式水平板防波堤。To improve the wave-dissipation and water permeability of the horizontal plate breakwater,we design a horizontal plate breakwater with semi-perforated on wave-facing side.Under different conditions of relative plate width,submerged depths,and wave heights,we use physical modeling tests to study the transmission coefficient K t,reflection coefficient K r,and energy dissipation coefficient K h of the two types of horizontal plate breakwaters including the non-perforated type and the semi-perforated on the wave-facing side type,and systematically compare the wave-dissipation performances of the two types of horizontal plate breakwaters.The results show that under test parameters,the transmission coefficient of the semi-perforated horizontal breakwater on the wave-facing side is smaller than that of the non-perforated horizontal breakwater,and the transmission coefficients of the two types of horizontal plate breakwaters both reach the minimum value when the conditions of relative plate widths are 0.166 or 0.212.While the trend of the reflection coefficients of the two types of horizontal breakwaters is similar,and the reflection coefficients of the semi-perforated horizontal breakwater on the wave-facing side are small.The overall reflection coefficients of the two types of horizontal plate breakwaters are similar in trend,and the overall reflection coefficients of the semi-perforated horizontal plate breakwaters on the wave-facing side are small;the overall energy dissipation coefficients of the semi-perforated horizontal plate breakwaters on the wave-facing side are larger than that of the non-perforated horizontal plate breakwaters,and they reach the maximum values when the relative widths are 0.166 or 0.212.The wave dissipation performance of the horizontal plate breakwater with semi-perforated on the wave-facing side is better than that of the non-perforated breakwater.
