Problems solved by technology

At present, research on the wave dissipation performance of arc-plate structures is mostly carried out from field tests and numerical simulations. In view of the large capital investment and long period of field tests in the specific implementation process, and the extreme wind and wave conditions in the open sea, it is difficult to carry out effective collection of measurement and test data
The input condition parameters in the numerical simulation are difficult to realize and there are many uncertain factors in the actual project, resulting in a certain gap between the numerical simulation results and the actual project; that is, the traditional breakwater structure wave dissipation performance device has low range accuracy and is not compatible with the installation of the arc plate structure. matching, expensive, etc.

Abstract

The invention discloses a device and a method for measuring wave dissipation characteristics of an arc-plate structure. The device is characterized by comprising an upper structure, the arc-plate structure, a lower structure, a wave height meter, a wave height data acquisition system and a wave water tank; the arc-plate structure is fixed from the lower portion through a specially-made stainless steel thin column, and the disturbance effect of a fixed support on water can be effectively weakened; a reflection coefficient of the arc-plate structure is calculated by adopting a Goda two-point method according to the wave height meter arranged in the wave water tank so as to analyze the wave dissipation characteristics of the arc-plate structure; the device for measuring the wave dissipation characteristics of the arc-plate structure is simple in structure and easy to operate, and the wave dissipation characteristics of the arc-plate structure can be comprehensively analyzed according to the calculated transmission and reflection coefficients.

Description

Technical field: [0001] The present invention relates to the technical field of measuring devices for wave-dissipating characteristics of structures, in particular to a measuring device and method for measuring wave-dissipating characteristics of arc-plate structures, which are used to test the external load (wave, water flow or both) of arc-plate structures in water tanks. Combined) measurement of wave dissipation characteristics. Background technique: [0002] With the intensification of the development and construction of large deep-water ports and wharves, the traditional gravity breakwater has a long construction period, is not suitable for construction in deep water and large waves, hinders the exchange of water bodies inside and outside the port area, and has a negative effect on water quality maintenance and ecological environment in the port area. The shortcomings such as adverse effects cannot meet the many requirements of marine engineering construction. The perm...
