桩基双挡板透空式码头波浪上托力试验研究
|
摘要
依托沈家湾客运码头拟建二期工程,通过物理模型试验,对桩基双挡板码头面板所受波浪力上托力进行研究。结果表明:相对波高(Hd)、相对波长(Ld)、后挡板结构形式、后挡板相对入水深度(t2d)均对码头面板及横梁上所受波浪上托力具有较为显著的影响。通过将最大上托波压强的试验值与现有研究成果进行对比,在后挡板相对入水深度≤0.65时,最大上托波压强的计算可以参考周益人的拟合公式;在后挡板入水深度>0.65时,最大上托波压强的计算可以参考过达的拟合公式。
Based on the second-stage engineering of Shenjiawan passenger terminal,we carry out a physical model experiment to study the uplift wave force distribution of the piled double baffles permeable wharf. The results show that the relative wave height( H d),relative wave length( L d),back baffle structure and relative underwater penetration of the back baffle( t2d) have obvious effects on the uplift wave force. Comparing the uplift wave force measured in the experiment and calculated by different formulas, we find that when the relative underwater penetration of the back baffle is equal to or less than 0. 65,the formula derived by Zhou Yiren is more applicable to calculate the biggest uplift wave pressure on the face plate. While the formula derived by Guo Da is more applicable when the relative underwater penetration of the back baffle is more than 0. 65.
