复杂波浪场中防波堤掩护效果的数值模拟研究
Numerical investigation of the performance of breakwaters in complicated wave fields
摘要
Abstract
The layouts of the breakwaters and the condition of the waves often make wave height chang at the berth,and thus disturb mooring task.Implements numerical simulations by MIKE21-BW based on Boussinesq type equations,to analyze the performance of breakwaters of a seaport project in South America both in complicated wave fields and various layouts.Results show that the layout 1 of breakwaters perform well in complicated wave fields,decreasing the significant wave height to the safe limit of short waves,ensuring operational efficiency and safety.However,this layout is less effective in shielding against infragravity(IG)waves with the increase of the period,the harbor may have operational problems in terms of the IG wave limit criteria.Layout 2 shows less reliable when compared to the layout 1,and can not meet the safe limit unsurprisingly.Layout 3 performs much well of decreasing significant wave height and IG waves height.关键词
