摘　　要：通过概化模型试验,研究了波浪正向入射时散体斜坡内法线方向最大波压力的衰减趋势,找出了影响波压力变化的相关因素。结果表明:破波压力从坡面向内部传递与方向、坡度没有明显关系,而与波陡、沿程相对位置相关。计算结果列出附表,便于工程应用。本研究成果为进一步研究波浪对散体斜坡破坏机理提供依据,对库岸工程防护有较高的应用价值。Based on comprehensive model tests of normally incident wave, the attenuation of the maximum wave force along inward normal to broken stone slope has been studied and its correlative factors has also been found. The findings show that the aforementioned wave pressure is independent of wave direction and broken stone slope, but influenced by the wave slope and the location of measurements. Calculation results are presented in the paper. The study provides the basis for further study on the destructive mechanism of broken stone slope and can be applied in engineering for reservoir hank protection.
