摘要

摘要: 应用斜向不规则波反射系数的改进两点法(MTPM),用模型试验研究了混凝土护面堤和块石护面堤波浪反射系数的频率谱和方向谱,结果表明,分析的反射系数随入射波频率的增加、结构坡度的减小和入射角的加大而减小.给出了波浪反射系数频率谱及其随Iribarren数变化的规律,提出了反射系数三维谱的经验公式,由此可定量地描述斜向不规则波的反射系数随无量纲特征参数Iribarren数和入射波角度的变化规律.

Abstract: The wave reflection coefficient frequency spectrum and directional spectrum for concrete shield breakwater and rubble mound breakwater have been investigated through physical model tests.Reflection coefficients of obliqueir regularwaves are analyzed with the modified two-points method(M T PM) proposed.The results show that wave reflection coefficient decreases with increasing of wave frequency and incident angle or decr easing of the structure slope.The reflection coefficient frequent spectrum and its variation with Iribarren number are given.An empirical 3-dimensional reflection coefficient spectrum is suggested,which can be used to illust rate quantitatively the variations of reflection coefficient with incident angle and a non-dimensional characterized parameter Iribarren number for oblique irregular waves.
