低桩承台直立结构波浪爬高与越浪量
|
摘要
针对国内规范缺乏直立式海堤波浪爬高和越浪量计算方法的问题,以深圳机场三跑道海堤设计断面为研究对象,通过物理模型试验,研究不规则波作用下低桩承台直立堤波浪爬高与越浪量,分析了波浪周期、堤顶超高、防浪墙挑檐宽度等影响因素与波浪爬高和越浪量的关系。采用最小二乘回归方法拟合,得出直立式海堤波浪爬高计算方法。运用多元线性回归方法拟合,得出直立式海堤越浪量计算方法。将越浪量计算值与试验值进行比较,表明两者具有较好的相关关系。
In view of the lack of domestic standards for wave run-up and overtopping discharge on low pile platform vertical sea dike calculation methods, based on the Shenzhen airport runway seawall design section,through physical model experiment,the paper researches irregular wave and low pile caps erect dike foreshore and the flow meter,and analyzes the wave period,crest superelevation,the width of wave barrier cornice influence factors relationships with foreshore and the flow meter. The method of least square regression is used to calculate the wave run-up of vertical seawall. By using the method of multiple linear regression,the calculation method of sea wall surface-breaking is obtained. The comparison between the calculated value and the test value shows that there is a good correlation between them.
