涌浪作用下岛式防波堤堤顶高程设计

岛式防波相对于常规的接岸式防波堤结构,其功能更为简单明确,即为单个码头提供掩护。在考虑到工程的整体经济效益,满足其特定使用功能的前提下,岛式防波堤堤顶高程设计标准可适当降低。基于实际工程项目,采用欧标计算防波堤堤顶越浪量及防波堤堤后有效传递波高。根据越浪量及有效传递波高的控制要求,确定岛式防波堤堤顶高程,并通过物理模型试验对岛式防波堤堤顶设计高程进行验证。

Elevation design of isolated breakwater under the action of swell

Compared to the conventional shore connected breakwater,the function of isolated breakwater is more simple and clear.Isolated breakwater is set for providing wave protection for a single jetty usually,considering the overall economic benefit on the premise of satisfying its specific function,the elevation design standard for isolated breakwater can be reduced appropriately.Based on the actual project,European standard is adopted in this paper to calculate the wave overtopping and wave transmission for isolated breakwater.Then,the isolated breakwater elevation is determined according to control requirements of wave overtopping and wave transmission,and design elevation of the isolated breakwater is verified by the physical model test.
