摘　　要：在对常规船舶，特别是超规范船舶，进行结构的直接设计时，首先要对波浪弯矩设计值作出估计。要确切地做到这一点，必须在明确船舶使命的前提下，设计人员要学会合理地选择好在船舶执行海域的海浪长期统计资料，然后根据船舶的装载工况，实际可能达到的航速，借用线性切片理论或非线性理论进行波浪弯矩的长期预报来确定设计值。本文就一艘大型集装箱船舶，按五个典型海域的海浪统计资料，对波浪弯矩及波浪合成弯矩作了长期预报计算，并与IACS的统一纵强度要求UR－S11的结果作比较和分析，给出了对船舶结构直接设计有指导意义的几点结论。The design values of wave - induced bending moments must he first estimated, When the direct structural design method was used for general ship designing, especially for ships beyond mies. In order to do so, designers must well recognize and rationally select the wave data of sailing areas, in which the ship will execute its mission. Then according to the loading conditions and the attainable velocities, with linear or non - linear strip theory and codes, the long - term predictions of wave bending moments are carried out to determine the design values. In this paper, five sets of wave data from different sources are analyzed. Based on the scatter diagrams of these wave data, the long - term wave bending moments, including wave - induced and slamming responses, are predicted for a large containership. The results are analyzed and compared with IACS - S11. Finally, some suggestions are made for direct design calculation of wave loads on ships.
