| 中文摘要: |
| Aiming at four typical permeable breakwater structures,a three-dimensional numerical model based on FLOW-3D is established to compare and analyze the wave dissipation performance and wave energy distribution characteristics of the structures under different wave periods.The numerical calculations indicate that:1)the curtain wall breakwater is suitable for short to medium waves,while the pile-supported permeable breakwater is only appropriate for short waves.The comb-type breakwater and double baffle pile-supported breakwater are applicable to waves ranging from short to long.2)The comb-type structure induces resonance under specific wave period,resulting in peaks and troughs in the transmittance and reflectance coefficients.3)Among the four perforated breakwaters,the double baffle pile-supported breakwater demonstrates superior wave attenuation under short waves,while the comb-type breakwater shows an edge in providing protection against medium to long waves. |
