Novel breakwater and design method thereof

Abstract

The invention discloses a novel breakwater and a design method thereof. The breakwater is arranged between a foreshore and a backshore, and comprises a foundation bed and a breakwater body, wherein a riverside slope protecting surface of the breakwater body comprises a slope-shaped riverside slope protecting surface and more than two arc-shaped riverside slope protecting surfaces which are connected together in sequence; a riprapping dike dam is arranged between the bottom end of the slope-shaped riverside slope protecting surface and the foreshore, and the top end of the slope-shaped riverside slope protecting surface is connected with the arc-shaped riverside slope protecting surfaces through a platform; and two adjacent arc-shaped riverside slope protecting surfaces are connected through a corner of the platform. Therefore, in the invention, as the riverside slope protecting surface is combined by the arc-shaped slope protecting surfaces and the slope-shaped slope protecting surface through the platform, the rise of waves and the wave overtopping rate of a breakwater top are effectively reduced through the wave breaking function of the arc-shaped slope protecting surfaces and the energy dissipating function of the slope-shaped riverside slope protecting surface; compared with the conventional breakwater, the novel breakwater can meet design requirements under the same condition more effectively based on a lower altitude of the breakwater top under the same design condition.

Description

technical field [0001] The invention relates to a new type of breakwater structure and design method, which can be widely used in coastal areas and areas on both sides of rivers, and is especially suitable for wave climbing, high wind speed, soft foundation, high dike fortification standards, or natural areas along the border. Areas with high environmental requirements can become part of urban construction. Background technique [0002] With the advancement of science and technology and the improvement of living standards, human research on breakwaters is also deepening. The structural section types of common breakwaters are as follows: [0003] (1) The steep wall breakwater occupies less land, the wave climb is smaller than that of the slope breakwater, and the elevation of the embankment crest is lower, but the foundation stress is large and concentrated, the settlement is large, the stability is poor, and it is easy to cause scour at the foot of the embankment.

AI Technical Summary

Problems solved by technology

[0003] (1) The steep-wall breakwater occupies less land, the wave climb is smaller than that of the slope breakwater, and the elevation of the embankment crest is lower, but the foundation stress is large and concentrated, the settlement is large, the stability is poor, and it is easy to cause scour at the foot of the embankment

[0004] (2) The slope-type breakwater has the advantages of small reflected wave, better anti-wave effect, and more uniform distribution of foundation stress, but it occupies a lot of land, the wave climbs higher, and the elevation of the embankment is higher.

[0005] (3) Hybrid breakwater, which is composed of steep wall type and slope type, has the advantages of steep wall type and slope type at the same time, but this kind of breakwater has turbulent wave flow at the turning point of slope change, and the structure is easy to be damaged

This single-function breakwater gradually cannot meet the needs of urban construction
