双排可调节浮箱式防波堤消浪特性试验研究

Experimental Study on Wave Dissipation Characteristic of a Double-box Floating Breakwater with Regulating Function

本文对一种双排可调浮箱式防波堤在规则波作用下的消浪效果开展模型试验研究。该防波堤结构由前后两排矩形浮箱构成。模型试验在波浪水槽中进行,主要针对不同布局方式下(即不同的前后箱间净距和后排箱吃水深度)的波浪透射系数,同时重点分析了波浪透射系数与入射波波坦、前后箱间净距、后排箱吃水深度之间的变化规律。

A model test is carried out to study the effect of wave dissipation of a double-box floating breakwater with regulating function under regular wave. The breakwater is composed of two rows of rectangular floating-boxes. The above model test is made in a wave flume. The results show the values of wave transmission coefficient based on different layouts of the floating boxes, i.e. the net space between the front and rear boxes and the draft of rear box. Meanwhile, the impact of incident wave steepness, net space between the front and rear boxes, and the draft of rear box on the wave transmission coefficient is analyzed in detail.
