| 摘 要： | 基于规则波对墩柱作用的理论,采用传递函数的方法,建立了多向不规则波浪对大尺度墩柱作用的计算模型。同时进行了物理模型实验,对数值计算结果进行了验证。实验结果和数值计算结果基本一致。结果表明多向不规则波浪与圆柱作用时,波浪的方向分布对圆柱周围的爬高具有明显的影响。研究成果可为实际工程设计时提供参考依据。

| Abstract: | Based on the linear theory of wave interactions with a large-scale vertical bottom-mounted cylinder, using the method of transfer functions, a number of models of multi-directional random wave interaction with a large-scale cylinder were established. A wave basin experiment was carried out, and the numerical calculation results were verified by the results of the physical experiment. The results from the numerical calculation and the experiment were essentially identical. The results show that wave directional distribution has significant effects on wave run-up when multi-directional irregular waves interact with a cylinder. Results can provide reference for the design of appropriate engineering projects. |
