双筒双板型浮式防波堤水动力试验研究

Experimental Stud yon Hydrodynamic Characteristics of Floating Breakwater with Double Cylinders and Plates

采用物理模型试验方法,研究一种由浮筒、竖直板、横向连接板组合而成的HDPE材质的新型浮式防波堤结构在海洋动力下的响应过程。结果表明,该结构透射系数及锚链拉力受波浪周期的影响较大,均随波浪周期的增大而增大;锚链刚性越大,对模型的约束越强,所受到的锚链拉力越大;波高的改变对透射系数影响不大,但锚链拉力随波高的增大而增大,且周期越大,锚链拉力随波高增长的速率越快。

The response process of a new type of HDPE floating breakwater structure composed of buoy,vertical plate and transverse connecting plate under marine dynamic is studied using physical model test.The results show that the transmission coefficient and chain force are greatly affected by wave period and increase with the increase of wave period.The greater the rigidity of the anchor chain,the stronger the constraint to the model,and the greater the force of the chain.The change of wave height has little effect on the transmission coefficient,but the chain force increases with the increase of wave height.Moreover,the longer the period is,the faster rate of the chain force increase with the wave height is.
