Problems solved by technology

However, the analytical method has very strict requirements on the shape of submerged dikes, which are usually limited to regular shapes such as rectangles and semicircles.
Numerical analysis methods have been well applied to trapezoidal rockfill submerged dikes and semicircular opening submerged dikes, but for multi-row submerged dikes, there are problems with too many grids and low calculation efficiency. question

Embodiment Construction

[0067] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0068] A method for analyzing the hydrodynamic characteristics of multi-row submerged embankments, specifically:

[0069] (1) Boundary value problem

[0070] In practical engineering, relative to the wavelength of the incident wave, the submerged embankment is generally very long in the axial direction. In this embodiment, it is assumed that the submerged embankment has an infinite length in the axial direction. Consider an obliquely incident wave with circular frequency ω and wavenumber k 0 , the angle between the incident direction of the wave and the x-axis is θ, and the components of the wave number on the x-axis and the y-axis are:

[0071] k 0x =k 0 cosθ (1)

[0072] k 0y =k 0 sinθ (2)

[0073] For the interaction between oblique incident waves and multiple ro...

Abstract

The invention provides a resonant reflection calculation method, device and electronic equipment for multi-row submerged embankments. The present invention first numerically solves the hydrodynamic characteristic parameters of a single row of porous submerged embankments, and then recursively calculates multiple rows of porous submerged embankments by using wide spacing assumptions The optimal design parameters of the multi-row submerged embankment are given. The invention has the advantages of high calculation efficiency, not limited by the influence of the shape of the submerged embankment, and can provide important reference suggestions for the engineering design of the multi-row submerged embankment.

Description

technical field [0001] The invention relates to a hydrodynamic characteristic analysis method, device and electronic equipment for multi-row submerged embankments. Background technique [0002] The top of the submerged embankment is submerged in water, which can effectively reflect and dissipate the wave energy and attenuate the wave height behind the embankment without affecting the seascape and the exchange of water bodies inside and outside the embankment. At the same time, the existence of the submerged embankment is conducive to the deposition of nearshore drifting sand at the submerged embankment, and also plays an important role in the project of promoting siltation and protecting the beach. Compared with the floating breakwater and the permeable breakwater, the submerged embankment has a weak wave-dissipating ability, and a single row of submerged embankments sometimes cannot meet the needs of the project. Therefore, it is necessary to set up multiple rows of submerg...
