通过物理模型试验研究中国《海港水文规范》(JTJ213-98)中斜坡式防波堤顶部胸墙波浪力计算公式在深水情况下的适用性。试验测量4种不同水深波浪作用下斜坡堤顶部胸墙的波浪力和作用高度。通过对胸墙迎浪面的波浪压强分布、总水平作用力和波浪作用高度的试验结果与《海港水文规范》结果的对比分析,发现胸墙迎浪面的实测波压分布不同于规范采用的均匀分布;规范计算得到的总水平力和波浪作用高度均小于实测值。本文改进规范中斜坡堤胸墙波浪力计算方法,使其更适用于深水堤顶部胸墙受力计算。
Abstract：Based on experimental results,this paper analyzes the suitability of Code method to calculate wave loads in deep water.Wave loads on crown wall of rubble mound breakwater and their action heights are measured for 4 different water depths and 3 different wave heights.Comparisons are carried out between the measured results and the obtained results by the Code.It is shown that differences exist for the wave pressure distribution,the value of wave loads and their action heights.The measured wave pressure distribution is no longer uniform,the values of wave loads and their heights are larger than the Code's results.A modification of the Code's method is made so as to make the Code's method more suitable for deep water.
