| 摘要: |
| 海面上的海浪经常有这种现象:几个波高较大的波一连串地相继出现,构成一个群,称为波群。波群不但有较大的能量,而且历时时间较长,因此有很大的破坏力,很多海上建筑物常常受其威胁或遭到破坏。
本文根据在渤海西部某石油平台上观测的海浪资料对该海域的波群进行了统计分析。观测所用的仪器是本所研制的CBS-IV型垂线测波仪。海浪传感器悬挂在石油平台下面,当地水深约20m。每天观测8次,大风天气加测,有时每小时观测1次。本文分析所用海浪记录是平均波高大于0.6m的记录。 |

| Abstract: |
| This paper reports results of study on the wave groups in the west of the Bohai Sea by statistical analysis, using data from wave observation records on an oil platform in that area.The analysis showed that, in the west of the Bohai Sea, wave groups average length 1. 56 waves; that in average, 9. 95 waves reappear; and that the length of a wave group including the maximum wave can reach 7 waves, average length of 2.03 waves. Comparison of the above results with those observed in Jiaozhou Bay, Lianyungang Bay etc, and results obtained from Rayleigh distribution and Weibull distribution that the average length of wave groups in the west of the Bohai Sea is larger than that observed in Jiaozhou Bay and Lianyungang Bay, and even larger than the calculated lenth. The average reappearance length of wave groups are less than those observed in Jiaozhou Bay and Lianyungang Bay. |
