摘　　要：通过物理模型试验的方法,研究深水斜坡堤的不同质量级配堤心石对不规则波传播的影响。对不规则波的外在规律进行了统计分析,且研究入射波周期、入射波高、堤心石质量级配等因素对防波堤透浪系数的影响,拟合得到考虑无因次参数H_i/d、gT^2/d及堤心石结构B/D_(50)等因素的不规则波透浪系数的计算经验公式,为防波堤工程建设和研究提供参考依据。For the rubble mound breakwater in deep water,the influence of the property of the core stone on the irregular wave propagation is studied in the way of physical model tests.The external regularities of the irregular wave are analyzed statistically,then the relations between the transmission coefficient of the breakwater,the period and the height of the incident wave, and the weight distribution of the core stone are discussed.Taking these dimensionless parameters H_i/d,g T^2/d and B/D_（50） into account,the irregular wave transmission coefficient empirical formula is put forward which is applied to irregular waves,so it can provide some reference for engineering practice of breakwaters and research.
