摘要
通过模型试验,对开缝板、开孔板、桩帽及靠船构件、桩基等不同码头结构的面板上波浪上托力的影响进行研究。试验结果表明,不规则波作用下面板开缝结构对波浪上托力有一定影响,开缝比较大时能相应地减小波浪力;桩帽及靠船构件的存在使得超高比较大,波浪难以冲击到面板上时,波浪上托力仍然能保持相当大的值;而面板上开孔结构、码头桩基对波浪上托力没有明确的影响。据此结果,对工程设计提出相应建议。
Results from experimental research on the effects of plate with gap behind, plate with holes, pile cap and berthing member, pile foundations on wave-induced uplift loads on deck of jetty are presented. It is demonstrated that there is a clear influence of setting gap between the deck and the shore on loads of irregular waves. Large gap can give rise to the uplift loads decrease. Relatively large uplift loads on superstructure at high air-gap level still can be measured is attributed to the contributions of wave forces on pile cap and berthing member even though for that situation waves can not reach the deck. Opening holes in deck and pile foundations show having little influence on uplift forces. Based on analysis above, suggestions were proposed as guideline for engineering design.
