斜坡堤挡浪墙波浪力计算方法比较

Comparison of wave force calculation methods for wave-retaining wall of slope breakwater

斜坡堤堤顶挡浪墙波浪力的计算,目前没有一种普遍适用的理论计算方法,文中结合实际工程的物理模型试验对目前常用的波浪力计算相关公式进行分析比较。分析结果表明,Pedersen法计算所得的波浪力与试验结果比较贴合,是目前比较稳妥的一种计算波浪力的方法,现行水文规范上波浪力计算方法得出的结果普遍偏小(相对物模试验结果),以上结果可为类似工程提供一定的参考。

At present,there is no general theoretical calculation method for calculating the wave force of wave-retaining wall at the top of slope breakwater.In this paper,the commonly used formulas for calculating wave force were analyzed and compared with the conclusions of physical model test of practical engineering.The analysis results show that the wave force calculated by Pedersen method is consistent with the experimental results,and is a reliable way to calculate wave force at present.The results obtained by the wave force calculation method on the current hydrological code are generally small(compared with the physical model test results).The above conclusions can provide a certain reference for similar projects.
