摘　　要：本文通过基于Boussinesq方程的平面二维数学模型研究了透空式防波堤的防浪效果。应用数值计算模拟了某港区分别在透空式防波堤和实体式防波堤掩护下其港内水域的波高分布。通过对不同周期入射波作用下港内比波高的对比结果,分析了防波堤防浪性能随入射波周期的变化特征,比较了不同周期入射波作用下实体式防波堤和透空式防波堤对堤后水域的掩护效果。2D plane numerical model based on Boussinesq equation is used to study the wave sheltering effect of permeable breakwater,simulate the distribution of wave heights behind the permeable breakwater and impermeable breakwater respectively.The wave heights under different periods of incident wave are compared in order to analyze the variation of wave sheltering effect of breakwater caused by the changed period of incident wave,and study the sheltering effect of permeable breakwater and impermeable breakwater under different periods of incident wave.
