波浪作用下高桩码头前波峰面高度研究

Study on front wave crest height of high-piled wharf under wave action

码头前沿波峰面高度是确定高桩码头面板高程的主要参数之一,主要由码头前沿纵梁、桩帽、靠船构件等上部结构引起的反射波与入射波叠加,产生水面壅高,而高桩码头结构的桩柱间距较大,对波峰面高度影响很小。本文根据微幅波理论和波能流守恒,推导了高桩码头前沿波峰面高度近似解析解,并通过物理模型试验资料验证,理论公式计算结果具有较好的精度,可为工程设计提供科学依据。

Wave crest height of hight-piled wharf is an important influential factor of the decking. The summer beam, pilecap and berthing member of the wharf apron may cause wave reflecxion, and the co-action of reflected wave and incident wave leads to the affluent levee of wave crest height. The large space between pvles of high-piled wharf eontribufes less to the wave crest height. Based on the small-amplitude wave theory and wave energy flax conservation, we obtainde the anylytical derivaxion of the wave crest height of hight-piled wharf. Which was then validatde hy the phgsical model test. The computation results hased on the theoretial formula are much accurate, thas may provide a scientific basis for the engineering design.
