    摘要
  • 摘要: 通过较系统的物理模型试验，对双层水平板式防波堤在斜向不规则波作用下波浪荷载随三个主要影响因子（相对入射角θ0、相对板宽B/L和相对波高Hs/D）变化的试验结果进行了分析讨论。结果表明：相对波浪入射角度θ0=0°、15°、30°、45°、60°时，整体波压包络沿板宽方向基本呈对称分布，且当θ0=30°时双层水平板四个表面整体波压包络要大于其它四个相对入射角的情况；从堤体同步压力分布特征上来看，斜向波浪作用下的较比正向入射时对结构的影响更为复杂，结构整体不仅受向上或向下亦或是顺时针倾倒的力的作用，而且存在由板中间向上下两侧分离及逆时针倾倒的趋势；从三个主要影响因子的角度分析讨论了结构总力的变化，并依据所得试验数据，计算并拟合出单位堤长上波浪力经验公式，为今后数值模型试验及工程设计提供试验依据。
    Abstract: In this study, systematic physical model tests were performed to investigate the wave forces on the twin-plate breakwater under irregular waves. Based on the experimental results, the effects of the relative plate width B/L, wave height Hs/D and incident angle θ0 on the wave forces were analyzed and discussed. The results showed s that:(1) The envelopes of the total wave pressure were generally symmetrical along the direction of plate width under the incident angles (θ0) being 0°, 15°, 30°, 45° and 60°. In particular, the envelopes of wave pressure at θ0=30° were larger than all other cases. (2) The synchronous pressure distribution of the breakwater under oblique wave action was more complicated comparing to the normal incident waves. (3) Based on data analysis, an empirical formula was obtained to estimate the total vertical force of the twin-plate breakwater. This empirical formula can be a good reference for the design basis of engineering applications under specified wave conditions.
