摘　　要：针对威海九龙湾岸滩治理工程,进行不同结构型式及不同高程离岸潜堤的物理模型试验。根据物理模型试验的结果,得出离岸潜堤透射系数Kt与主要影响因子的相互关系。得出影响潜堤透射系数最主要的因子为相对堤顶水深(a/Hi),在一定水位条件下,相对堤顶长度(B/L)也能影响透射系数。借助MATLAB数学软件平台,将数据进行回归分析,得出不规则波作用下潜堤透射系数的经验公式,为此类工程设计提供参考。We analyzed transmission coefficients of different structural types and crest level submerged dykes designing in Jiulong Bay of Weihai. Change regulation of Transmission coefficients K, and important factors of submerged dykes was obtained through model tests. Such as, the relationship of K, and a/Hi （a is the height from the still water level to the top of submerged dykes, H is the wave height）, B/L（B is the submerged breakwater crest width, L is the wavelength）. Empirical formulas of wave transmission through a submerged dykes under the action of irregular wave was provided scientific basis for the engineering design and construction.
