摘要
根据影响因素理论,进行水槽试验.选取梯形潜堤作为研究对象,采用规则波作为入射波,探讨波浪三要素(波高、水深和周期)变化时潜堤前、后波高变化规律.选取相对水深a/Hi、波陡Hi/L及相对安放位置dl/SL作为研究重点,研究结果表明:堤顶相对水深是影响潜堤消浪效果的最主要因素;且随着堤顶水深增大,潜堤消浪效果减弱.
According to theoretical analysis, the main effecting wave-damping factors are a/Hi and Hi/L. Based on these theories, the flume experiments were designed. A trap- ezoid submerged breakwater is selected as the object of study. The incident wave is a regular wave. The wave-damping pattern is studied by changing the wave factors (wave height, water depth, period), a/Hi ,Hi/L and dl/SL are selected as the research priority. The results show that the a/Hi is the most important effecting wave-damping factor, the wave dissipating is significantly weakened while the water depth of submergence is increased.
