| 摘 要： | 透空式防波堤利用上部结构的挡浪板实现挡浪消波,为港区提供良好的泊稳条件,桩基和挡浪板部分入水会改变建筑物局部水域的水动力特性。在有透空式防波堤的海域进行二维潮流数值模拟时,分别利用了等流量法和等效阻力法对挡浪板进行概化,将挡浪板对水流的阻碍作用等效为通过改变地形和当量糙率来模拟对水流的影响;研究分析了透空式防波堤概化处理后,挡浪板对周围水域的水动力特性的影响。结果表明两种方法均能模拟出挡浪板的阻水效果,其中等效阻力法物理概念清晰,模拟结果更符合实际规律。

| Abstract: | The permeable breakwater with wave baffle can provide moderate sea for berthing by weakening
the wave energy. Hydrodynamic property of flow closed to the structure is strongly affected for the resistence
produced by the immersed pile and wave baffle. To study the affected hydrodynamic property of flow by wave panel
in two-dimensional tidal numerical model, the wave panel is generalized by the method of discharge-equivalent and
resistance-equivalent respectively, which equals approximately the retaining effect caused by wave panel to similar
effect caused by adding depth or adding roughness. The results show that both methods can simulate the waterresistance
effect of wave panel, and the simulation results of resistance-equivalent method is more consistent with
practical rules. |
