波浪和垂直透空式防波堤相互作用研究

Research on Wave and Vertical Permeable Breakwater Interaction

分析了三种安装形式的垂直透空式防波堤在桩吃水、水深比和开孔影响系数变化时所受的波浪力变化,用MATLAB语言编程并计算绘制出透射系数和反射系数曲线。在不规则波的分析中采用谱分析理论,求得水平方向的累积频率波浪力。研究表明:几种安装形式的防波提中,悬空安装的透空式防波堤所受波浪力最小。计算结果可以给防波提的相关设计提供参考。

Three different installation forms of vertical permeable breakwater are analyzed which suffer forces from waves. Using MATLAB programming language to calculate the change of the wave force of vertical permeable breakwater when the draft of the pile and the water depth ratio T/d, the openings influence coefficient G alone change. With irregular wave analysis using the theory of spectral analysis, their cumulative frequency of the hori- zontal direction is achieved. Analysis showes that the truss-breakwater wave forces sufferes minimum, then provides references to the design of the breakwater.
