    摘要:

    近些年来,随着海洋资源开发的深入,兴建了大量海洋工程结构物,波浪在结构上的涌高是结构设计时所关心的重要问题之一。本文以典型圆柱结构为对象,对其在不同参数不规则波浪作用下进行了长时间物理试验模拟,以得到稳定的涌高统计。分析了波浪涌高的影响因素,比较了不同经验公式的预测效果。研究结果表明波浪非线性对涌高有较大影响,波浪陡度越大,大波峰出现概率越大,进而较大涌高出现概率也增大。考虑二阶因素的涌高计算公式能够较好预测波浪涌高,并推荐了涌高计算公式。结果将为海洋工程结构设计提供依据和参考。

    Abstract:

    In recent years, with the development of marine resources explorement, a large number of marine engineering structures have been built. The run-up of wave on the structure is one of the important issues in structural design. In this paper, a typical cylindrical structure was taken as the object, and long-time physical simulations were carried out under the action of irregular waves to obtain stable wave run-up statistics. The influence factors of wave run-up were analyzed, and the prediction results of different empirical formulas were compared. The results showed that the greater the wave steepness is, the greater the probability of large wave crest is, and the greater the probability of wave run-up is. And the wave instability has little effect on surge height. The wave run-up calculation formula considering the second-order factor can better predict the wave run-up height, and the wave run-up calculation formula was recommended. The results will provide the basis and reference for the structural design of offshore engineering.
