摘　　要：通过不规则波作用下波浪水槽物理模型试验,对开孔双挡板式高桩码头透浪特性开展研究。将试验结果与各家公式的计算结果进行对比分析,认为规范公式并不适用于开孔双挡板式高桩码头透浪系数的计算。Kriebel公式计算结果与试验结果吻合良好。在Kriebel公式的基础上,提出了计算一定波浪条件下开孔双挡板式高桩码头透浪系数的半经验公式,可为类似条件下的工程建设提供计算透浪系数的依据。The wave transmission coefficient through double immersed vertical barriers with holes of high- piled wharf is studied through the physical model experiment in wave flume under irregular wave action. By comparison of experimental results with different theoretical calculation methods of wave transmission coefficients, the calculation method of wave transmission coefficient in the Code of Design and Construction of Breakwaters turns out to be not suitable for high-piled wharf with double immersed vertical barriers with holes. The results of Kriebel formula are in good agreement with experimental results. On the basis of Kriehel formula, the paper proposes a semi- empirical formula of wave transmission coefficient under certain wave conditions, which may serve as a reference for the engineering practice under similar conditions.
