摘要
对我国海洋工程现行规范与行业标准中关于设计重现期的规定进行了总结分析。从工程使用期与危险率的角度，确定多种海洋环境条件的联合重现期。基于二维等效最大熵分布，对渤海菜区域极值波高与风速的联合设计参数进行了估计。计算结果表明，具有相关性的二维变量，重现期较小的环境要素值的组合，往往产生较大的重现期，由此可使平台结构投资成本降低。
The definition of design return period in existent codes and industry criteria is Summarized. Joint return periods of various ocean environmental conditions are determined from the view of project life and danger risk. Based on the equivalent bivariate maximum entropy distribution, joint design parameters of wave height and wind speed occurred in some place of Bohai Sea are estimated. The calculating results show that the combinations of environmental factors with smaller return periods usually lead to larger joint return periods. That will make the investment of ocean platform lower.
