| Summary: | 碩士 === 東南科技大學 === 防災科技研究所 === 99 === This study used cross-section tank, the use of pore structure of permeable breakwater as set, the main breakwater of energy dissipation of pore permeability for a series of hydraulic model experiments and research, and according to their different pipe diameter , Length and angle combinations into a variety of other conditions of permeable breakwater, and with regular waves, to investigate the pore structure of wave and energy dissipation generated by the interaction effect of the change of its wave energy dissipation of the role of such a breakwater And effect.
Reasonable use of water tank layout and experimental test section measured waveform to Goda 【1】 (1976) proposed two methods for experimental data analysis, for regular waves on the breakwater permeability pore of tilting and the difference of which Sex. Regular waves with regularity and consistency of the waves, when the tube diameter and length and angle changes, and the incident wave of wave height and there will be some relationship between the wavelength, the reflectivity, transmission and energy also will be a relatively abrasion The waveform changes. The experimental results of the analysis of the most effective, available aperture, length and angle of the best configuration to Montreal was used as reference for coastal protection, making them more security and the economy.
The results showed that: the pore inclined permeable breakwater on the occurrence of the minimum reflectivity cycle have different effects, its long period of relatively easy to reduce the wave, the wave is short-cycle the other hand, there is no significant effect of energy dissipation.
