| 摘 要： | 波浪力是作用在离岸建筑物上的主要荷载，准确预测作用在结构上的波浪力在实际工程设计中极其重要，它决定着该结构是否能够安全可靠地工作。目前的研究大多集中在单向波浪作用下结构物所受的波浪力，而真实的波浪是三维多向不规则波浪。基于物理模型实验，系统地研究了多向不规则波浪作用下大尺度墩柱所受波浪力的特性。结果表明波浪的方向分布对波浪荷载具有明显的影响，尤其是对横向力，在方向分布宽度较大时，作用在墩柱上的横向力可达此时作用在墩柱上正向力的40%，这在实际工程设计中不能忽略。

| Abstract: | Wave force is the main load on the offshore structure, accurate predictions the wave loads on structures are significant in practice engineering design. Most of the research associated with wave interaction with structures has been focused on unidirectional waves. But in reality, sea waves are multidirectional. Based on a physical model experiment, the characteristics of wave force loads on a large-scale cylinder under multidirectional random waves action are studied systematically. The result shows that the wave directionality has an obvious impact on wave loads, especially on the transverse forces. For the wider directional distribution, the transverse force cannot be ignored anymore and is about 40% of the normal force. This fact needs to be taken into account in order to make accurate predictions of the wave loading on cylinders in practice. |
