【 摘 要 】

Through the physical model test method, the wave dissipation performance and mooring force of porous floating breakwater under regular waves are analyzed and compared with the traditional pontoon floating breakwater. The results show that for long waves with small wave height in the tests, the transmission coefficient of porous floating breakwater is 0.5%∼4% smaller than traditional floating breakwater. The porous floating breakwater cannot achieve effective wave dissipation under most conditions mainly because of the small height out of the water. The mooring force of porous floating breakwater can be reduced 3%∼5.5% with splayed mooring system. The research content in this paper provides a theoretical basis for the design and engineering application of porous floating breakwater.
