| 摘 要： | 为求得充分反映长江口水域渡浪特征的特定波谱,对该水域波浪谱进行细致分析,选用PM谱、新规范谱(海大谱)、J谱(JONSWAP谱)拟合实测谱,估算3种谱型的参数,并将谱参数与特征波要素进行比较,确定它们之间的关系.最后根据拟合结果提出不同范围的推荐谱型,建议在1.27＜p＜6.77时采用海大谱,p不在上述范围内时采用J型谱.

| Abstract: | Wave spectrum was carefully analyzed in the water at Changjiang estuary in order to achieve specific model of spectrum suitable for the water.The parameter of spectrum-model was reckoned by comparing the practical wave spectrum with PM-spectrum,J-spectrum and New criterion-spectrum.In addition,by comparing the parameter of spectrum-model with the key factors of the representative wave,the relationship between them was found out.Furthermore,the recommended spectrum-model was put forward in different ranges a... |
