【摘要】：基于AQWA軟件,對(duì)島礁地形下帶系泊系統(tǒng)的多浮箱浮式棧橋進(jìn)行了運(yùn)動(dòng)響應(yīng)的數(shù)值模擬,并與帶島礁地形模型試驗(yàn)的響應(yīng)幅值算子(RAO)進(jìn)行了對(duì)比分析,為浮式棧橋在實(shí)際海洋環(huán)境中的施工和運(yùn)營(yíng)安全等作準(zhǔn)確預(yù)報(bào).研究結(jié)果表明,基于AQWA軟件,文中數(shù)值方法可有效模擬島礁對(duì)多浮體的繞射和輻射等干擾;由于海底地形變化的影響,波浪將發(fā)生折射、繞射、反射等一系列的復(fù)雜變化,同時(shí)海底傾斜會(huì)對(duì)系泊纜繩張力造成影響,從而會(huì)影響浮橋的運(yùn)動(dòng)響應(yīng).數(shù)值模擬島礁地形影響下多體浮橋的運(yùn)動(dòng)響應(yīng)結(jié)果與水池試驗(yàn)得到的數(shù)值對(duì)比吻合良好.
[Abstract]:Based on AQWA software, the motion response of floating pontoon trestle with mooring system under island and reef terrain is numerically simulated, and compared with the response amplitude operator of terrain model test with reef. It is an accurate prediction for the construction and operation safety of floating trestle in the actual marine environment. The results show that, based on AQWA software, the numerical method in this paper can effectively simulate the diffraction and radiation of islands and reefs to multiple floating bodies, and a series of complex changes, such as refraction, diffraction and reflection, will occur due to the influence of submarine topographic changes. At the same time, the submarine tilt will affect the mooring cable tension, which will affect the motion response of the floating bridge. The results of motion response of multi-body pontoon bridge under the influence of island and reef topography are in good agreement with those obtained by tank test.
