摘　　要：通过物理模型试验，研究了不规则波作用下光滑不透水单坡和复坡上的波浪爬高，分析了主要影响因素波陡、坡度、波浪入射角、平台宽度和高程对波浪爬高的影响规律，得到了海堤结构波浪爬高的计算公式及其不同累积率换算关系，并提出了多级平台海堤断面波浪爬高计算方法，可适用于复杂海堤断面的爬高计算，与40多个实际工程的模型试验结果对比，具有较好的计算精度，可供工程设计参考。Based on the physical model experiment, this paper studies the wave run-up of the single sloping and composite sloping seawall under the irregular wave action, analyzes the influence of main factors such as wave steepness, slope, wave incident angle, as well as the width and elevation of the platform on the wave run-up, and obtains the calculation formula for the wave run-up of multi-platform seawall and accumulative frequency function. Comparing with the results of more than forty model experiments, this method has a better calculation accuracy, thus may serve as a reference for the engineering design.
