| Abstract | In this thesis the trianglar stepped submerged breakwaters with different heights , sizes, and directions were respectively put into a two-dimensional wavermaker. Through irregular waves with different cycles and heights, the wave gauge and the measuring scale were used to measure the reflection and transmission when the waves passed through the trianglar stepped submerged breakwaters; the effect to reduce wave energy of setting stepped submerged breakwaters was also compared. Through repeated experiments and analysis, it was found that the stepped submerged breakwaters indeed effectively reduced wave energy, and so did the submerged breakwater with a smooth surface, especially the ones with large steps. According to the experiments with different waves heights and cycles, the analysis of the results is that the energy dissipation of code F is the best. During the process of the experiments in this study, it is observed that the energy-eliminated function of stepped submerged breakwaters is strong enough to replace wave-eliminated blocks and breakwaters on the coast. Traditional wave-eliminated blocks and breakwaters are neither beautiful nor environmentally friendly, and they destroy the marine ecosystems easily; furthermore, in rescue they increase the difficulty as well as the danger of rescue personnel. |
