有护面块体掩护的斜坡堤弧形胸墙波压力研究

弧形胸墙可以有效减小斜坡堤越浪、降低胸墙顶高程，因此越来越多地在工程中采用。但在规范中对斜坡式防波堤弧形胸墙波压力计算方法没有明确规定。结合工程实例，将弧形胸墙波压力物理模型实测结果与现行规范直立胸墙波压力计算结果进行对比分析，总结了该工程防波堤弧形胸墙在有掩护条件下所受的波压力情况，供工程设计参考。

Pressure of arc parapet covered by accropodes on sloping breakwater

Arc-shaped crest wall can effectively decrease overtopping across slopping breakwater and help reduce elevation of crest wall. So it is more and more used in coastal engineering. But there is not any provision on how to calculate wave pressure on arc-shaped crest wall in current standards. Based on a physical experiment on an actual project, this paper presents measured pressure results along the arc-line of the crest wall, which is further compared with the calculated results following the standard provisions on vertical crest-wall. Finally, pressure distribution on the crest wall is summarized. These results can be used as reference to other similar projects.
