摘　　要：通过物理模型试验,对孤立波作用下浮式单排水平板、浮式双排水平板、浮式三排水平板和浮式开孔水平板防波堤的消浪性能开展研究,对比分析在不同相对波高和系泊线倾角下4种浮式水平板防波堤的透射系数、反射系数、波能耗散系数和系泊张力。结果表明,浮式单排水平板防波堤的透射系数最小,浮式三排水平板防波堤的透射系数最大;相较于浮式单排水平板防波堤,浮式双排水平板、浮式三排板和浮式开孔水平板防波堤的系泊张力均明显减小;适度调整系泊线的倾角能够改善浮式水平板防波堤的消浪效果和改变系泊线张力特性。We study the wave attenuation performance of single-row floating flat-plate,double-row floating flat-plate,triple-row floating flat-plate,and perforated floating flat-plate breakwaters under the action of solitary waves through physical model tests,and compare and analyze four types of floating plate breakwaters in terms of their transmission coefficients,reflection coefficients,wave energy dissipation coefficients,and mooring tensions under different relative wave heights and mooring line inclinations.The results show that the transmission coefficient of the single-row floating flat-plate breakwater is the smallest,while that of triple-row floating flat-plate breakwater is the largest.Compared to the single-row floating flat-plate breakwater,double-row floating flat-plate,triple-row floating flat-plate,and the perforated floating flat-plate breakwaters exhibit significantly reduced mooring line tension.Moreover,moderately adjusting the inclination of the mooring line can also improve the wave attenuation effect of the floating plate and change the characteristics of mooring line tension.
