碩士 === 東南科技大學 === 防災科技研究所 === 98 === The experiment of porous pipe breakwater are being in this article by the differ in porous size and pipe length, combination of differ random wave conditions, the characteristic of porous pipe breakwater are the interaction of porous article and it’s effect, compared by waveform’s changed, reflection rate and transmittance rate, to discussed the attenuation effect and interaction for differ porous pipe article. In this experiment, put five wave gauges in the wave flume, in order to measure the wave change, and combination of differ random wave conditions, differ in porous size and pipe length and article’s width, to discussed the waveform’s changed, reflection rate and the attenuation effect. In case, when change the porous size and pipe length of the porous pipe article, will affect the reflection rate. In fact, the wave will perform a random and irregular, but follow the experiment data to this article by a serial of analysis and research, and the reference the before research, we can more understand the porous pipe breakwater’s effect by reflection rate and wave-wave interactions.
