摘　　要：为研究正向入射波压力在散体斜坡上的变化规律,通过室内模型试验获得了大量试验数据。在数据分析时引入了波压陡的概念,论证了在波浪传播过程中可运用波压陡与波陡的函数关系来分析内部压力场的变化规律,并运用最小二乘法拟合出波压陡与波陡之间的关系曲线,总结出正向入射波打击散体斜坡面时波压陡随波陡变化的经验公式,从而可直观地通过波陡得到波压陡进而求得散体斜坡上打击点的最大波压力,为今后的研究和设计提供了重要参考。In order to research the law of positive incident wave pressure on medium slope,a lot of experimental data are obtained through indoor model test.The concept of pressure wave gradient is introduced for data analysis.And then this paper demonstrates the function relationship between pressure wave and wave gradient which can be used to analyze the law of internal pressure field in the spread process of waves.At the same time,the least square method is applied to fit the relationship curve between wave pressure and wave gradient.Finally,it sums up the empirical formula of wave pressure and wave gradient when positive incident wave hits medium slope.Furthermore,the maximum pressure wave in hitting point of medium slope is easily obtained with the wave pressure gradient.So,it provides important reference for future research and design.
