半潜式平台结构强度分析中的波浪载荷计算

The Wave Load Calculation in the Analysis of StructuralStrength of a Semi-submersible

分析了海洋工程受波浪载荷的情况,阐明具体计算理论和方法。对于小结构物,波浪的拖曳力和惯性力是主要分量,波浪载荷用Morison公式计算。对于大结构物,波浪的惯性力和绕射力是主要分量,波浪载荷用线性绕射理论计算。大型半潜式平台的波浪载荷计算采取Morison公式和势流理论相结合的方法。

The wave load acting on offshore structure is analyzed and the detail calculating methods and theories are described.For slender structures,Morison′s equation is used and for large volume structures,diffraction theory is used.The combination of these two methods is used for calculation of wave load acting on the semisubmersible platform.
