一种新型浮式防波堤的试验研究

Experimental Research of a New Type Floating Breakwater

浮式防波堤具有不影响相应海域物质交换、造价随水深变化不大等优点,但其消波效果较差且对锚泊系统要求高等因素,减缓了它向实际工程转化的步伐。本研究综合考虑阻挡反射、紊动耗能、波峰耗散多种消波机理,进而提出一种由多菱形模块拼装而成的多孔浮式防波堤结构,并对该结构进行物理模型试验。试验结果表明,该结构型式的浮堤消波效果好且受波浪力小。

Floating breakwater doesn＇t affect the water exchange and has little increase on cost with increscent water depth,but the factors of the poor ability of wave absorption and the high requirement for the mooring system have limited its development. Presents a new type floating breakwater made from a lot of diamond modules. The mechanisms of reflection, turbulent motion and wave crest dissipation are considered in the design. The results of the physical model experiment indicate that the floating breakwater is good at wave absorption and Suffer small wave force.
