直墙堤前不规则波浪形态特性的研究

Study on Conf iguration of Irregular Waves in Front of Vertical Wall

通过二维不规则波模型试验,测定分析直墙堤不规则波浪形态特性,给出低、中、高基床条件下的形态界限。试验表明,直墙堤前不规则波浪仍存在非破碎波与破碎波,其形态特性可由波列的特征波表示,不规则波破碎界限上限与规则波一致,下限与上限差别较大,取上限对工程是安全的。

Through two-dimensional model test of irregular waves, configuration of irregular waves in front of vertical wall breakwater is surveyed and analyzcd,and conf iguration limits of wavcs uncler 1ow, middle and high foundation beds are given respectively.Experiments show that there exist breaking wave non-breaking wave in the irregular waves in front of vertical wall breakwater.The configura-tion feature of irregular waves may be indicated by the-characteristic wave of the wave train,in which the upper limit of the breaking irregular wave is coor-dinate with the regular wave, but the upper limit is quite different from the lower limit,so it is on the safe to structure when the upper limit is taken.
