摘要
垂直挡板式透空堤作为一种新型的透空式防波堤结构,通过将挡浪板垂直设置于波能最集中的水体表层来消减波浪,透浪系数是其最关键的指标。通过物理模型试验,分析不规则波作用下入射波高、波周期、挡板相对入水深度、相对堤宽、相对挡板超高、相对面板超高等因素对垂直挡板式透空堤透浪系数的影响规律,并在Wiegel公式的基础上拟合了垂直挡板式透空堤透浪系数的计算公式。可作为今后类似透空式防波堤结构透浪系数的近似估算,具有一定的参考价值。
Vertical baffle permeable breakwater is a new style of permeable breakwater structure,which reduces wave height by vertically setting the baffle in the water surface which concentrates most of the wave energy,and the wave-permeating coefficient is the most crucial index. The influence factors of the wave-permeating coefficient of the vertical baffle permeable breakwater under irregular waves are analysised through the physical model experiment,which considers the incident wave height,the wave period,the relative immersed depth of the baffle,the relative width of the breakwater,the superelevation of the baffle,the superelevation of the deck,etc.The formula for calculating the wave-permeating coefficient is obtained on the basis of the formula of Weigel,which can be used as an approximate estimation for the wave-permeating coefficient of similar permeable breakwaters in the future.
