【摘要】：基于AQWA软件,对岛礁地形下带系泊系统的多浮箱浮式栈桥进行了运动响应的数值模拟,并与带岛礁地形模型试验的响应幅值算子(RAO)进行了对比分析,为浮式栈桥在实际海洋环境中的施工和运营安全等作准确预报.研究结果表明,基于AQWA软件,文中数值方法可有效模拟岛礁对多浮体的绕射和辐射等干扰;由于海底地形变化的影响,波浪将发生折射、绕射、反射等一系列的复杂变化,同时海底倾斜会对系泊缆绳张力造成影响,从而会影响浮桥的运动响应.数值模拟岛礁地形影响下多体浮桥的运动响应结果与水池试验得到的数值对比吻合良好.
[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.
