摘要: 摘 要 在海岸工程上,透水潛堤除了有海岸保護及防災之功能外,並兼具可豐富海岸生態資源,在整合性海岸保護系統案例中,透水潛堤常被設置於海堤前方,但透水潛堤與海堤之間波場變化卻未受到重視。在海堤前設置透水潛堤影響作用下,本文以試驗探討研究三種物理現象,即透水潛堤後面的波場變化、水位抬升和海堤上的波浪溯升。本研究以海堤與潛堤兩結構之間二種不同距離以及改變透水潛堤幾何形狀進行試驗探討之,結果顯示,當入射波通過潛堤時,由於波浪在潛堤上方碎波,故潛堤後方波浪能量較為減小,但透過波受到海堤反射作用,潛堤與海堤間波浪呈現明顯的震盪現象;而在潛堤後方發現平均水位有抬升之現象,且隨著空間變化分佈,最大水位抬升發生於透水潛堤與海堤之中間區域。本研究發現最大水位抬升高度隨著潛堤沒水深度增加而減少,本文由試驗結果迴歸得經驗公式,以描述最大抬升水位和潛堤沒水深度關係。另外海堤面上的波浪溯升現象,本研究亦發現最大的波浪溯升隨著潛堤 沒水深度增加而增加。
ABSTRACT The submerged permeable breakwater is increasingly regarded by coastal engineers for use against the beach erosion and the coastal hazard, even for the coastal ecological restoration. However, the wave transformation between a submerged breakwater and a seawall has not received much attention though the submerged structure may be located in front of a seawall in case of the Integrated Shore Protection System. Three problems are associated with the use of the submerged breakwater in front of a seawall. There are wave transformation and the water piling-up behind the submerged breakwater, and the wave run-up on the seawall. The experimental results of these three phenomena are reported in this study. Two distances between these two structures, and varied geometrics of the submerged permeable breakwaters were considered in the experiments for a seawall. Due to the wave reflection from the seawall, the significant fluctuation of the wave height behind the submerged breakwater is found. But the wave heights are much smaller than that of the incoming wave due to the wave breaks over the submerged breakwater. The piling-up of water is found behind the submerged breakwater, and where the maximum piling-up occurs about in the middle region between these two structures. It is found that the maximum height of piling-up decreases with the submergence of the breakwater. The empirical equation is presented in this paper for the relationship between the maximum piling-up and the submergence of the breakwater. The height of the wave run-up on the seawall is dependent upon the wave height behind the submerged breakwater. It is found that the maximum run-up increases with the submergence of the breakwater due to its relative larger height of the transmitted wave.
