摘　　要：为了明确斜坡堤弧形胸墙越浪量及波压力的变化规律,采用波浪水槽试验测量了弧形胸墙的越浪量和波压力。试验从斜坡堤弧形胸墙前的掩护程度等因素入手对弧形胸墙的返浪效果及波压力进行初步研究,得出不同掩护程度弧形胸墙的越浪量及波压力,发现掩护程度越好,弧形胸墙所受波压力越小;半掩护情况下越浪量最小,为实际工程设计提供了依据。Wave flume experiment is conducted to determine the variability of the overtopping discharge and wave pressure on a sloping breakwater with an arc parapet.To start with the various coverture layouts,the wave return effects and wave pressures are preliminarily studied in the experiment.It is learnt from the measurements of the overtopping discharges and wave pressures corresponding to the various coventure layouts that better coverture will result in less wave pressure on the arc parapet and the over topping discharge becomes the least in the semi-coverture case.This study might be used as a reference in the engineering and design practice.
