中文摘要
本研究之目的在於探討規則波下發生移動的漂沙量與波浪條件間的關係。廖等(2008)雖然考慮不同海底初始坡度,但不知底質粒徑對移動沙量的影響。
研究由水工模型試驗探討規則波浪作用對不同底質粒徑底床沙層遷移之影響。以性質相近的二色試驗沙,舖設1/45動床斜坡,使移動沙層可視化,並使用影像分析移動沙量。分析波浪作用而造成的底床移動沙層體積,並探討顆粒粒徑與碎波渦流係數、碎波可動參數的關聯性,冀望藉由同性質(中值粒徑、比重)的兩色(黑、白)砂粒探討規則波與移動沙量之間的關係。
在波浪尖銳度0.0065~0.0584、中值粒徑0.110mm至0.237mm的研究成果顯示,雖然顆粒大小不同,但平均移動沙量變化率隨造波時間成指數函數狀態收歛。顆粒粒徑因素不影響渦流係數與平均移動沙量間的線性關係,其經驗式為 q= 6.486*10^-5*εb。然而隨著顆粒粒徑的增大,可動參數與單次移動沙量間的線性斜率關係亦增大,斜率由小顆粒至大顆粒分別為q=5.103*10^-6Θb、q=1.139*10^-5*Θb 、q=1.933*10^-5*Θb 。建議未來應對更大顆粒及更大比重的底質進行試驗研究。
Abstract
In the study, the thickness of wave moved-sediment layers was measured under regular wave conditions as well as the initial slope of sea bed with grain size of medium diameter 0.237mm and 0.128mm. The initial bottom slope ( tanα) is 1/45, and nineteen wave conditions were studied. For each case, we analyzed the results after about 28800 waves were made.
Sands are similar density and grain size but different colors. After wave action, the clear boundary between the two layers (two different colors) of sands will be mixed into gray color by wave-induced vortex.According to unmoved-layer(white) and gray-layer to get the total wave-moved sediment quantity.
Finally, we get the relationship between the wave-moved sediment quantity per wave( q) and two parameters( εb and Θb ) which were established by Liao (2005, doctorate draft). The grain size does not affect εb , and we get the q= 6.486*10^-5*εb . The relationships between and : 0.110mm gets q=5.103*10^-6Θb , 0.128mm gets q=1.139*10^-5*Θb, and 0.237mm gets q=1.933*10^-5*Θb .
