Experimental Research Of Floating Breakwater

Floating breakwater is a useful structure which can be applied when building a standing breakwater is unnecessary, or in water area requiring good water exchanging quality. It is widely used in coastal engineering and aquatic breeding, etc.Through the experiment conducted in a wave flume, this article studies the wave dissipation characteristic and surface pressure distribution of a fixed two-dimensional floating breakwater. According to the research target of this experiment with the experimental equipment and testing method, a square-box floating breakwater is designed, which has the same width as the wave flume. Also, the wave profile data and surface pressure data are acquired by wave gauges and pressure sensors separately.The analytical solution of the transmission coefficient can be solved. According to the investigation of the wave profile data acquired by wave gauges, variation of transmission coefficient with different parameters is studied here. By comparing with the analytical solution, the variation of the transmission coefficient with cycle and draft is procured. On the other hand, according to the surface pressure data acquired by pressure sensors, the variation characteristic and pressure distribution of the surface pressure is studied. Also, the position of biggest kinetic pressure and absolute pressure is revealed.
