高桩码头上部结构波浪力物理模型试验研究

Physical model test of wave force on upper structure of high-piled wharf

在不同水位、相同波浪要素组合条件下进行波浪对码头上部结构作用力的模型试验研究,得到上部结构所受最大波浪水平力、最大波浪上托力、最大波浪水平力对应的波浪上托力以及最大波浪上托力对应的波浪水平力,分析最大波浪水平力和最大波浪上托力之间的相位差;并对最大波浪上托力和理论值进行分析比较。试验结果表明:随着水位的增高,作用在码头上部结构的波浪力先增大后减小,在设计高水位时,码头上部结构受到的波浪力最大;最大波浪上托力和最大波浪水平力并不同时出现,存在相位差。

According to the model experiment on the wave forces on the upper structure of the wharf under combined conditions of different water stages and the same wave parameters, we obtain the maximum horizontal wave force, the maximum uplift wave force on the upper structure of wharf, the uplift wave force corresponding to the maximum horizontal wave force, and the horizontal wave force corresponding to the maximum uplift wave force. The phase difference between the maximum horizontal wave force and the maximum uplift wave force are analyzed, and the tested data for the maximum uplift wave force is compared with the theoretical value. The experimental results show that with the increase of water level, wave force on wharf upper structure increases first and then decreases. In the design high water level, wharf＇s upper structure suffer the maximum wave force; the maximum uplift wave force and the maximum horizontal wave force do not appear simultaneously, there is a phase difference.
