    摘要:

    弧形挡浪墙与传统的直立式挡浪墙相比,具有能显著减少堤顶越浪量、降低堤顶高程、节省工程投资并兼具较好的景观效果等优点。但是现行JTS 145-2-2013《海港水文规范》并未给出弧形挡浪墙波浪力的计算方法。结合工程实例,通过不规则波作用下波浪水槽物理模型试验,对无掩护的弧形挡浪墙波浪力开展研究。将试验结果与规范直立式挡浪墙波浪力计算结果进行对比分析,总结了本工程防波堤弧形挡浪墙在无护面块体掩护条件下所受的波压力情况,可为类似工程的挡浪墙设计提供参考。

    Abstract:

    Compared with the conventional vertical parapet wall, the arc parapet wall can reduce effectively overtopping, the elevation of slopping breakwater, the investment of engineering and enhancing the landscape of the embankment. But current Code of Hydrology for Sea Harbor hasn’t provided the calculation method of wave forces on arc parapet wall. Based on the project example, the wave forces on arc parapet wall under no protection of armor block is studied through the physical model experiment in wave flume under irregular wave action. By comparison of experimental results with calculated ones following the Code of Hydrology for Sea Harbor provisions on vertical parapet wall, the chacacteristics of wave pressure distribution and wave forces on the arc parapet wall are summarized, which can serve as a reference for engineering practice under similar conditions.
