| 摘要 |
The present addition relates to a device for attenuating the sea swell, comprising, according to the main patent, a slightly submerged plate (1) held fixed on rigid supports (2), its upstream and downstream edges being turned upwards, so that the incident swell cannot be propagated freely over the plate. A "fixed water wall" (4) is formed between the bottom (3) and the plate (1). The upstream edge of the latter has a recess (6) which reduces the width of the plate above a residual tab-shaped part (7), so that the upstream edge (1a) is divided into a primary upstream edge (1'a) and a secondary upstream edge (1"a) set back at a specific distance (a) relative to the primary upstream edge, this distance being selected so as to reduce or cancel the amplitude of the chopping occurring as a result of the combination of the swell components in line with the primary upstream edge (1'a), namely the incident component (Fi) and the components (Fr, F1, f1) attributable to the presence of the device. <IMAGE> |
