摘　　要：在海岸及海洋防灾减灾以及设计波浪的推算中,最大波高的计算是至关重要的。基于瑞利分布的最大波高公式,不能体现谱宽因素的影响,由该公式得出的理论最大波高要高于实际值。通过分析挪威海10年实测波浪定点观测数据,发现随着谱宽的增加,H_(max)/H_s逐渐减小,并拟合出包含谱宽参数的最大波高公式,简单易用,实用性强。The maximum wave disaster as well as for the calculation height is significantly important for of design wave. The maximum wave distribution can not reflect the influence caused by obtained by that formula is Norwegian Sea, we find that formula with spectral width the prevention of coastal and marine height formula based on the Rayleigh spectral width.Thus, the theoretical value of maximum wave higher than the real value in practice. Through analyzing the lO-years＇ measured Hmax/Hs decreases gradually with the increase of spectral width.A maximum wave as an influence factor is deduced, which is easily to use and has good practicality. height data of height
