  本文旨在探討波浪通過透水潛堤前後之變化特性與其透過率。透水潛堤建立於台南水工試驗所大型斷面水槽之斜坡底床上,在81組規則波與不規則波試驗當中,主要可將波浪條件區分為堤頂碎波與堤後碎波兩種型態,分別探討其經過透水潛堤前後之波形、波譜之變化特性及波浪透過率並建立一波浪透過率經驗式。
  實驗結果顯示兩種波浪型態通過潛堤之後均衍生較高頻波動,其中波浪為堤後碎波者,透過波之主頻、倍頻處有明顯之尖峰值,而波浪為堤頂碎波者,僅於透過波之主頻處有明顯之尖峰值,高頻處能量為不規則分佈。兩種波浪型態之透過波頻譜能量均隨距潛堤愈遠,而呈透過波之主頻能量漸增,較高頻能量漸減之現象。經無因次參數分析,當波浪為堤後碎波時,波浪尖銳度對波浪透過率之影響比堤頂沒水深與入射波高之比值、堤趾水深與入射波高之比值對波浪透過率之影響較顯著;而當波浪為堤頂碎波時,波浪透過率受到堤頂沒水深與入射波高之比值、堤趾水深和深海波高比值影響遠比波浪尖銳度大。最後,藉由堤頂沒水深與入射波高之比值、堤趾水深與入射波高之比值兩因子建立本實驗潛堤之波浪透過率經驗式。
  The characteristics of the transformation and associated attenuation when waves passing over a submerged breaker were investigated experimentally. A permeable submerged breakwater was constructed on a sloping bottom at the SuperTank of the Tainan Hydraulics Laboratory. Totally 81 test conditions, including both regular and irregular waves, were conducted. The test conditions were mainly categorized into two groups, which are those waves broken on submerged breakwater and those waves broken after submerged breakwater. The subject is a matter of study the changes in evolutions of the wave form, the correspondent energy spectrum and the transmission rate through a submerged breakwater and submit the result into an empirical wave transmission equation formulae.
  The experimental results show that the high frequency components were generated after the above-mention waves passing through the submerged breakwater. The main frequency energy and the secondary frequency energy of the waves broken on submerged breakwater are obvious high. Only the main frequency energy of the wave broken after submerged breakwater is high, and the high frequency energy region is irregular distributed. As the submerged breakwater moves far against the shore, the transmission waves main frequency energy increases and the high frequency energy decreases. Based on dimensional analysis, in the case of waves broken after submerged breakwater, the relationship between wave transmission and wave steepness are more effective then the ratios of submerged water depth and breakwater depth to the incident wave height. However, in the case of waves broken on submerged breakwater, the wave transmission related to the submerged water depth and breakwater depth are more effective than to the wave steepness. Finally, the empirical formulae were obtained in this paper.
