浅水区域浮箱式防波堤结构形式的试验研究

介绍了2种浮箱结构型式的防波堤(L型中浮箱和L型边浮箱),3种类型(L型边浮箱、H型边浮箱、T型边浮箱)的浮式防波堤,对浅水区域浮箱式防波堤结构形式进行了实验室物理模型试验研究。得到了在规则波作用下的浮式防波堤的消浪效果和透过率。本次试验结果表明,在浅水波情况下,相同周期时的防波堤越宽波浪的透过率较小;同一形式尺寸的防波堤,透过率随着周期加长而逐渐增大。

Experimental Study on Structure Types of Pontoon Breakwaters in Shallow Water

The paper introduces two structure types of pontoon breakwater(L-middle pontoon and L-side pontoon) and three types of floating breakwater(L-side pontoon,H-side pontoon and T-side pontoon).The physical model test on structure types of pontoon breakwater in shallow water was done in the laboratory.The effect of wave breaking and transmission coefficient of floating breakwater under the action of regular waves are obtained.The results shows that the wider the breakwater is,the less the transmission coefficient of waves is under the condition of shallow water with the same period.Concerning the same type and same size breakwater,the transmission coefficient will increase with extension of wave period.
