摘要
通过波浪断面物理模型试验,测得开孔沉箱结构码头在不规则波作用下的波浪反射系数和码头前沿波峰面高度。采用单因次分析法,在研究开孔沉箱基本结构对反射系数的主要影响基础上,着重探讨透空式上部结构对反射系数的影响;同时采用同样的方法研究波峰面高度的影响因子。最终拟合出这两个物理量的简化计算式,并用理论方法对波峰面高度的拟合公式加以验证且建立了其与反射系数之间的关系,为工程设计提供参考。
Through the wave cross-section physical model test, the wave reflection coefficient and wave crest height of the open caisson structure under irregular wave action can be measured. Through the single factor analysis method, this paper mainly analyses the influence of different factors related to the permeable upper structure to the reflection coefficient based on the study on the basic structure of open caisson structure; and at the same time analyses the influence of factors to the wave crest height in the same way. Finally, it fits out formulas to compute the two physical quantities, proving the formula about wave crest height by theory and establishing the relationship between it and reflection coefficient. The test results may serve as reference for the engineering design.
