本文在波陡 H/L=0.055—0.092,相对水深d/H=1.6—2.8,顶墙前相对水深d1/H=0.2—0/36,对迎浪面开孔率为24—72%的范围内,分别在顶墙底开孔及不开孔进行试验得到以下结果: 1)透孔消浪顶墙稳定重量比实体顶墙小。 2)透孔消浪顶墙的临界稳定重量随前墙开孔率的增大而减小。对于顶墙 In this paper, the wave steepness H / L = 0.055-0.092, the relative water depth d / H = 1.6-2.8, the relative depth d1 / H = 0.2-0 / 36 in front of the top wall, Range, respectively, at the bottom of the top wall openings and non-perforated test to get the following results: 1) Through-hole noise elimination roof solid wall weight less than the solid wall. 2) The critical stability weight of the through-hole wave-elimination top wall decreases with the increase of the aperture ratio of the front wall. For the roof
