Abstract

The invention discloses a wave dissipation structure suitable for sloping sea dikes. The structure comprises a sloping dike and a siltation promoting and beach protecting longitudinal dike arranged on the front beach land of the sloping dike, wherein the outside slope surface of the sloping dike is built by two stages of slopes and a wave dissipation platform between the two stages of slopes; barrier board protection slopes are paved on the surfaces of the two stages of slopes; an upper wave dissipation structure is arranged on the barrier board protection slope of the upper slope of the wave dissipation platform; a lower wave dissipation structure is further arranged on the barrier board protection slope of the lower slope of the wave dissipation platform; and further on, a middle wave dissipation structure is added to the outside edge of the wave dissipation platform. The structure has the following beneficial effects that: the physical model experiments prove that the wave dissipation effect is obviously improved; the wave overtopping rate can be reduced by 65-89%; and on the one hand, the structure can be used for heightening and reinforcing the sloping dike, and on the other hand, the dike elevation can be reduced and the investment can be saved if the new dikes adopt the wave dissipation structure and the wave dissipation method.

Description

Technical field:

[0001] The invention belongs to the fields of water conservancy engineering and coastal engineering, and is suitable for wave-dissipating structures newly built or reinforced by slope-type dams such as estuaries, lakes, coasts, and the like. Background technique:

[0002] The dikes along the river and coast, the breakwaters of ports and waterways, etc. all require to control the elevation of the dikes and reduce the surge as much as possible, that is, there is a requirement for wave dissipation.

[0003] see figure 1 and figure 2 As shown, at present, a large number of slope-type dams 10 are used in water conservancy projects and coastal engineering, and the outer slopes of most slope-type dams 10 adopt the structural form of two-stage slopes 11, 12 plus wave-dissipating platforms 13, and the wave-dissipating platforms 13 Located between two grades of slopes 11, 12 (see figure 1 ). In order to further dissipate waves, some projects set up silt-promoting...
