波浪作用下趸船对高桩码头的受力影响

Influence of pontoon on high-piled wharf under wave force

在以往研究成果的基础上,通过对不同水位波浪作用下码头前无趸船、有趸船但不与码头连接和有趸船并采用引桥连接3种布置方案进行物理模型试验,测量了码头受到的水平力和上托力,分析了3种布置方案趸船对码头受力的不同影响。试验结果表明:趸船和引桥的传递作用会使码头受到的水平力增大,趸船对波浪的阻碍作用会使码头受到的上托力减小。

When designing a high-piled wharf with pontoon, we need to take the influence of pontoon into account, but there is little research on this project. Based on that, we conduct the model experiment under combined conditions of different water stages and same wave parameters. The model experiment includes three projects, i.e. without pontoon, only pontoon, and pontoon with steel approach bridges in front of the wharf. According to the model experiment we obtain the horizontal wave force and the uplift wave force of three experimental schemes and analyze the effect of pontoon. The experimental results show that the transmission effects of pontoon and approach bridges increase the horizontal wave force to wharf and the blocking effects of pontoon to wharf decrease the uplift wave force to wharf.
