不同质量级配堤心石对波浪传播影响的试验研究

通过物理模型试验的方法,采用规则波研究了深水斜坡堤堤心石物理特性的变化对于波浪传播的影响。在无越浪的前提下,主要讨论了斜坡堤透浪系数与入射波周期、入射波高、质量级配等因素的关系。根据上述研究成果,拟合得到了考虑无因次参数H_i/d、gT~2/d及堤心石结构B/D_(50)等因素的透浪系数计算经验公式,为今后防波堤工程建设及科学研究提供一定的参考依据。

Experimental study on influence of wave propagation by different weight distributions of core stone

For the rubble mound breakwater in deep water,the influence of the property of the core stone on the wave propagation is studied using regular waves in physical experiments.Without overtopping,the relations between the transmission coefficient of the rubble mound breakwater,the period and height of the incident wave,and the weight distribution of the core stone are discussed.An empirical formula of transmission coefficient in function of dimensionless parameters Hi/d,gT2/d and B/D50 are fitted,which provide reference for breakwater construction and scientific research.
