摘要
文章延续林蔚等^([1])针对直立活动折叶板开孔式结构物的消波特性做进一步探讨,并以水工模型实验方式比较不同长度单消波室的消波能力,发现适当的折叶板配重,可以让消波室内外波动达到同步而提升其消波效果,但是消波室长度也可能造成舱内的水体振荡与相位变化,而有较大的反射率。综合检讨后,获致结论为消能结构物的消波机制系由开孔岸壁及消波室的消波功能与排水机能所共同组成,消波室长度不一定能消减波能反而激活振荡。如能分项加强其消波工,应可有效提升消波能力。
By conducting a series of hydraulic model test about the wave dissipation ability of the flap plate type vertical perforated structure which was proposed by Lin et al [1].and proved to have satisfactorily wave dissipation ability.The purpose of this study was to improve the higher reflection at the shorter/longer wave periods under the influence of the different single wave chamber width.The test results show quite different tendency of reflection curve from that of Lin et al [1].The wave dissipation mechanism of the structure is found to be the integrate effect of the wave dissipation ability of perforated wall equipped with flap plates and that of the wave chamber,and the function of discharge system,improper chamber width might cause the internal resonance.If enhancing their wave absorbing function,the whole performance might be improved.
