Description

technical field [0001] The invention belongs to the technical field of experimental devices, and relates to a device for simulating a surface wave caused by a huge displacement of a water body caused by a tsunami or an earthquake in a laboratory, in particular to a laboratory solitary wave automatic generation device. Background technique [0002] Solitary wave is a unique wave phenomenon in nature, which can occur in both rivers and oceans. Its wave fronts are all above the still water surface, moving forward at a certain speed and keeping the waveform unchanged, and the wavelength is very long. As a wave with strong nonlinear characteristics, solitary waves can be used to describe surface waves caused by huge displacements of water bodies caused by tsunamis or earthquakes. At present, the methods commonly used in the laboratory to simulate solitary waves are: the traditional method of heavy objects falling into the water and the push-plate wave-making method. The former h...

AI Technical Summary

Problems solved by technology

At present, the methods commonly used in the laboratory to simulate solitary waves are: the traditional method of heavy objects falling into the water and the push-plate wave-making method. The former has poor repeatability, and the latter cannot achieve a large wave height-to-water-depth ratio due to the limitation of the stroke of the wave maker. For the generation of solitary waves, neither of the two methods can meet the test requirements of solitary waves with relatively large wave height and water depth
