关于海岸水工建筑物顶部单波越浪量的研究

在防波堤与堤后结构物的安全性评价和堤顶行人与车辆等的危险因素分析中,单波越浪量比常用的平均越浪量能更真实地反映出堤顶越浪的影响,是更为合适的越浪量评估指标。重点介绍直立堤和斜坡堤上单波越浪量的计算方法,并通过具体算例对相似的计算方法进行对比分析,针对不同计算方法的选用原则提出相关建议,可供防波堤工程设计参考。

Study on Single Wave Overtopping at Top of Marine Structures

Based on safety evaluation of breakwater and back-seawall structures, by analyzing dangerous factors such as pedestrians and vehicles at the top of seawall, wave overtopping impact at the top of seawall can be measured exactly through single wave overtopping instead of current mean wave overtopping. The former one is regarded as more suitable wave overtopping evaluation index. The methods to calculate single wave overtopping on vertical seawall and slope seawall are introduced as key point. The similar methods are analyzed and compared each other in an example. In addition, relevant suggestions are made to the rule for selecting different calculation methods, which will provide the reference for the design of breakwater projects.
