摘　　要：本文用统计计算和后报方法，获得了本海域不同海区多年年极值波高（Ｈ１／１０）资料。用Ｐ－Ⅲ型和短期测波资料频率分析方法，估算了各海区的设计波高，并依据文献［３］计算出对应的平均周期。用Ｋｏｌｍｏｇｏｒｏｆｆ适合度方法检验所得的结果表明，依Ｐ－Ⅲ型方法拟配的理论频率曲线与经验点十分吻合，从而确定了本海域不同海区最佳的设计波浪。分析本海域年极值波浪的基本特征表明，本海域除了渤海湾北部海区以外，主浪向一般为ＮＮＥ向，渤海海峡区的年极值波高和设计波高均为最大，而向莱州湾及渤海湾沿岸海区逐渐减小；在沿岸海区，由龙口至黄河口一带的极值波高较大。In this paper, the annual ex+reme wave heights (H1/10)for many years in the different areas of this region are obtained based on the statistical calculation and hindcasting technique. Using the P- Ⅲ type method and a frequency analysis method for measuring short-term wave data,the design wave heights are estimated in the different areas and their corresponding mean periods are calculated according to reference[3].The checked results obtained from Kolmogoroff's method of fit degree show that one of the theoretical frequency curves fitted from P-Ⅲ type method is more agreeable with the empirical points. Thereby,optimal design waves are determined in the different areas.The analyses of the basic characteristics of extreme waves in this region show that except for the north areas of I3ohai Bay, the direction of the dominant wave is usually NNE in this region. Both the annual extreme and design wave heights are the largest in the Bobal Strait and then decrease slowly toward the coastal areas of Laizhou Bay and Bobal Bay. The extreme wave heights are relatively large in the coastal areas from Longkou to the mouth of the Huanghe River.
