【摘要】 采用凝集质量法对浮式防波堤系泊缆有效张力进行求解,利用大型水动力分析软件Orcaflex建立浮式防波堤模型,求解分析不同波浪方向作用下浮式防波堤整体水动力性能及系泊缆有效张力变化情况,并针对浮式防波堤端侧缆失效后情况进行对比分析,得出在方向为67.5°的波浪作用下横摇运动最为剧烈,且浮式防波堤两端缆绳的张力在两种浪向下均大于两侧缆绳张力等结论。分析结果对浮式防波堤安全建设及使用提供一定理论依据,对浮式防波堤在港口建设中的应用具有较好参考价值。更多还原

【Abstract】 The effective tension of the floating breakwater mooring line is solved by the lumped-mass method. The large hydrodynamic analysis software Orcaflex is used to establish the floating breakwater model, the overall hydrodynamic performance of floating breakwater and the change of effective tension of mooring cable under different wave directions are solved and analyzed. The side failure cable of the floating breakwater is also compared and analyzed. The results show that the rolling motion is the most violent under the wave direction of 67.5 degrees, and the tension of the cable at both ends of the floating breakwater is greater than that of the cable at both sides of the breakwater under both waves. The analysis results provide a theoretical basis for the safe construction and use of floating breakwaters, and have great reference value for the application of floating breakwaters in port construction.更多还原
