摘　　要：设有挡浪板结构的透空式防波堤适用于水深较大的海域,且具有较好的消浪效果。采用物理模型试验,探究具有双侧挡浪板结构的透空式防波堤透浪系数与反射系数的影响因素与规律,研究包括外侧与内侧挡浪板入水深度,水平板板宽,结构上部挡浪墙的高度与位置,水平板超高与波浪要素等因素。通过比较各家透浪系数的理论计算公式与实验结果,进行透浪系数的计算方法研究,给出修正Wiegel公式拟合双侧挡浪板透空式防波堤的透浪系数计算公式,供工程设计参考与进一步研究。Penetrated breakwater with wave barrier is applicable to deep waters,which has good wave dissipation effect.Physical models are conducted to research the influence factors for penetrated breakwater with double barriers.The results show that the key factors are the lateral and inside immersed depth of barriers,the width of horizontal plate,the height and position of block wave wall on the structure,the height of horizontal plate,Waves parameters,etc.On the basis of comparison of different theoretical calculation methods of transmitted coefficient and experimental results,the modified Wiegel Formula is given for penetrated breakwater with bilateral barriers.The method can be used as reference for further research and engineering design.
