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。
弧形胸牆可以有效減小斜坡隄越浪、降低胸牆頂高程,因此越來越多地在工程中採用。但在規範中對斜坡式防波隄弧形胸牆波壓力計算方法沒有明確規定。結閤工程實例,將弧形胸牆波壓力物理模型實測結果與現行規範直立胸牆波壓力計算結果進行對比分析,總結瞭該工程防波隄弧形胸牆在有掩護條件下所受的波壓力情況,供工程設計參攷。

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.
