摘　　要：透水防波堤堤心抛石体内的水体运动和压强分布规律,在海岸工程的整体安全中占据着非常重要的地位。采用物理模型试验方法,对规则波作用下,波浪与抛石透水堤的相互作用进行了研究,讨论了波高H与周期的平方T^2之比H/(gT^2)以及沿堤心的横向坐标值x_0与堤心石粒径D之比x_0/D对透水防波堤堤心压强衰减系数的影响。在前人研究成果的基础上,提出了改进的堤心压强计算公式。The water movement and pressure distribution in the core of permeable breakwater plays a very important role in the overall safety of coastal engineering.We investigated interaction between wave and rubble permeable breakwater under the action of regular waves through a series of sectional model tests,explored the attenuation coefficient of the pressure on permeable breakwater core,which is influenced by the ratios of wave height to the square of wave period H/(gT2)and the horizontal coordinate of dike to the grain diameter of core material x0/D.The main contribution of this work is to propose improved empirical formulas of core pressure based on previous researches.
