摘要
通过波谱分析的方法，研究了堤前能谱，反射系数和底流速的各自分布规律，分析了它们的相互关系：从堤前能谱表达式推导出反射系数的表达式，并将该反射系数用于求堤前任意位置的底流速，给出了堤前与入射波的底流速的统一形式．实验及计算表明，在无基床条件下得到的堤前能谱和底流速关系可推广到低基床的相应情况．
This paper investigated tile law of distribution of energy spetrum, reflection coefficient and bottom velocity by the method of wave spectrum. The reflection coefficient is derived from the formula of energy spectrum in front of vertical breakwaters and has been used in calculation of bottom velocity. The results of calculation and tests show that the proposed formulas of energy spectrum and bottom velocity can also be used in the case of vertical breakwater with lowelevation foundation.
