摘　　要：通过波浪物理模型试验,研究桩基透空式结构的影响因子(包括波陡、挡板的相对入水深度、开孔情况),给出了各个因素对透射系数的影响规律。结果表明,挡板的入水深度越大,透射系数越小;波陡越小,透射系数越大;挡板开孔对透射系数影响相对较小,但可有效减小波浪作用力。将试验结果与各家透浪系数的理论计算公式以及规范所给的经验公式进行比较,结果与Wiegel公式计算结果吻合较好,Wiegel公式可为工程设计提供参考。This paper investigates the impact factors of permeable pile structure （ including wave steepness, the relative immersed depth of the piled baffle and openings） using the physical model experiment method, and gives the influential law of various factors on the transmission coefficient. The experimental result indicates that the relative immersed depth of the piled baffle and wave steepness have a negative correlation with the transmission coefficient. The impact of baffle openings for the transmission coefficient is relatively small, but it can effectively reduce the wave forces. Comparing the experimental result with various wave transmission coefficients＇ theoretical formula and empirical formula given by the specification, the Wiegel formula matches well with the result got in this study, so it can be used for reference for the design.
