摘要
为研究不同的数值模拟方式对直立堤波压力的模拟情况,以及直立堤上波压力随入射波周期变化的情况,本文基于XFLOW与FLOW-3D分别建立数值水槽,模拟了二阶斯托克斯波与直立堤相互作用的情况,并对结果进行了分析。研究表明:模拟所得结果均与物理试验结果吻合较好,但FLOW-3D模拟结果的误差更小;此外,在入射波波高不变的情况下,随着入射波周期的增加,作用于防波堤迎浪面各测点的波压力整体趋势基本相同,波峰作用时,波压力逐渐增大,且增幅均匀减小;在极端高水位时波浪周期T达到120%,或者设计高水位时波浪周期T达到130%的情况下,波压力基本稳定;波谷作用时,波压力先减小,当周期T达到110%后,波压力基本稳定。
In order to find out the simulation results of wave pressure on a vertical breakwater by different numerical methods and the variation of wave pressure with the increase of incident wave period,two numerical water flumes were set up based on XFLOW and FLOW-3 D,separately.It is showed that both methods agreed well with the physical test results,but the error of the results simulated by FLOW-3 D were smaller.In addition,,the trend of wave pressure under each case was basically unchanged with the constant incident wave height as the wave period increased.During the wave peak,the increasing range of wave pressure was gradually reduced,and the wave pressure basically not changed with the increase of wave period until 120%T under extremely high water level and 130%T under design high water level.During the wave valley,the wave pressure reduced at first,then reach to a steady status after 110%T.
