摘要
以沈家湾客运码头拟建二期工程为依托,通过物理模型试验研究了桩基双挡板透空式码头的挡板所受水平波浪力的分布规律,并将试验值与公式计算值进行对比。结果表明,相对波高H/d、相对波长L/d、后挡板结构形式、后挡板相对入水深度s2/d对前后挡板所受水平波浪力均有显著影响。此外,孙龙、盛祖荫基于桩基码头物模试验拟合的水平波浪力公式比海港水文规范推荐的公式及合田良实公式更适用于前挡板的水平波浪力计算。
Based on the second-stage engineering of Shenjiawan passenger terminal, physical model experi-ment was carried out to study the horizontal wave force distribution of the piled double baffles permeable wharf.And the comparison of the horizontal wave force measured in the experiment and calculated by different formulaswas done. The results show that relative wave height（H/d）, relative wave length（L/d）, back baffle structure and under-water penetration of the back baffle have the obvious effects on the horizontal wave force. Furthermore, the formuladerived by Sun Long and Sheng Zuyin based on the piled wharf experiment is more suitable for the horizontal waveforce calculation of the piled double baffles permeable wharf than the formula suggested by Code of hydrology forsea harbor and derived by Goda.
