摘　　要：带挡板透空式防波堤是一种新结构形式,它既能实现水体交换又能对港内进行掩护,实现这些功能取决于挡浪板入水深度是否设计合理。通过理论计算,并结合工程波浪数模及物模的试验研究成果进行对比分析,得出挡浪板不同入水深度对港内掩护、波高分布情况及越浪量的影响。结果表明,码头外侧挡浪板入水深度增加,码头后方泊位处波高有所减小且码头结构所受水平力增大、越浪量增大、作业时间减少,对港内掩护效果加强。The permeable breakwater with baffle is a new structural type.It can conduct water exchange and protect the harbor at the same time,and the realization of these functions depends on the reasonable design of baffle’s depth.Based on the theoretical calculation,we carry out the comparative analysis of the results of engineering wave mathematical model and physical model,and obtain the influence of different water entry depth of wave baffle on the wave cover,wave height distribution and wave overtopping in the harbor.The results show that the increase of water entry depth of wave baffle outside the wharf decreases the wave height at the rear berths of the wharf,increases the horizontal force on wharf structure,increases wave overtopping,decreases operating days and enhances protection of the harbor.
