| 摘要: |
| 双平板式透空堤具有较为优越的消浪性能备受专家学者关注。目前关于其消浪性能的评价多采用透射波高法开展，仅考虑波高一个参数。本文采用透射波高法、波浪能量法和波能流法分别对平板式透空堤的消能效果进行评价，结果表明，综合考虑波高、水深和周期三个参数的波能流法更加全面与深入。探讨了双平板式透空堤迎浪向与背浪向处波能流的主要影响因素，结果表明，相对板宽、位置参数和波高大小对波能流的影响较板间距和潜深更加显著。 |

| Abstract: |
| Experts and scholars have understood the excellent wave dissipation performance of double-flat-slab permeable breakwater. At present, the transmission wave-height method is used to evaluate wave attenuation performance, and only one parameter of wave height is considered. In this study, the transmission wave-height, wave-energy flow, and wave-energy flow methods are used to evaluate the energy dissipation effect of the flat permeable breakwater. The results show that the wave-energy flow method that considers wave height, water depth, and period is the most comprehensive and in-depth method. The main influencing factors of wave-energy flow in the upstream and downstream directions of the double plate permeable breakwater are discussed. The results show that the influence of relative plate width, location parameters, and wave height on wave-energy flow is more significant than that of plate spacing and depth. The research results of this study can provide some reference for the study of the energy dissipation effect of the open dike. |
