【摘要】 在海岸工程中，直立堤是经常被采用的防波堤型式。本文通过模型试验，对斜向波与防波堤的相互作用进行研究。 在模型试验中，采用了高基床和低基床两种基床形式，进行了在不同的波浪高度、波浪周期和斜向波角度的条件下，规则波、不规则波和方向谱对直立堤作用的测试。通过模型试验，得到各种条件下的斜向波对防波堤的波浪力和反射系数。 通过试验数据的分析，导出防波堤在斜向波下与在正向波下受力相比系数，得到斜向波对防波堤的波浪力与斜向波角度的相关关系，并获得反射系数与不同斜向波角度的关系。更多还原

【Abstract】 In coastal structures, the vertical wall is often used. Based on the model experiments, we analyzed the action of incident wave on vertical wall.In the model experiments, foundation with a small height and foundation with a large height were used. Both regular wave and irregular wave experiment have been done under the conditions including different wave height, wave period and angle between the main direction of wave propagation and the normal of structure axis on plane. In these experiments, wave force acting on vertical wall and coefficients of reflection were measured.Through the analysis of experimental data, we got the wave force coefficients between normal incident wave and obliquely incident wave, and relation between the wave force and the oblique angle. And the influence of angle towards coefficients of reflection were gotten.更多还原
