摘　　要：通过对某5万t级大开口型船舶的各种波浪诱导载荷长期预报，详细讨论了不同波浪散布图、装载工况、航速、水动力计算理论和短峰波对波浪诱导载荷长期预报极值的影响，指出了一些值得注意的问题，以期对类似船型的船体波浪诱导载荷预报提供有用的参考。Based on the long-term distribution of wave induced loads for a 50000DWT ship characterized by large hatch openings,the influence of different wave scatter diagrams,hydrodynamic theories for calculating the transfer function of wave induced loads,cargo loading conditions and speeds,as well as short crested wave,on the long-term extreme values is studied.Some remarkable problems involved in the long-term prediction are pointed out.The conclusions obtained are available for reference for similar type of ships.
