【摘要】 波浪载荷作为海洋平台在生命期内最重要的载荷形式,正确评估海洋平台的波浪载荷对结构的安全性具有重要意义。本文对一座深水半潜平台的波浪载荷进行模型试验和数值计算验证研究,模型缩尺比为1∶40。采用三维势流理论对半潜平台的波浪载荷进行数值仿真验证计算。验证结果表明本次模型试验方法较好地模拟了半潜式平台所承受的波浪载荷,其研究成果,可为半潜平台的设计提供支持。更多还原

【Abstract】 Wave load as the most important load form of offshore platforms whole life, properly assess the wave loads on offshore platform safety is great significance. Wave load model tests and numerical calculation on a deepwater semi-submersible platform were carried out with model scale ratio 1∶40. Using three-dimensional potential flow theory the numerical simulation of wave load for semi-submersible platform was calculated. The results show that this model test method can get real character of wave load, and the research results may be helpful for semi-submersible platform designer.更多还原
