Abstract:The research on the wave and tide coupling simulation technology can provide a technical support for the construction of coastal disaster prevention system,disaster assessment,early warning and response.It is of great significance to prevent and reduce the storm tide and typhoon wave disaster along the sea platform.We review the research results of storm surge and wave physical model test,analyze the latest research progress and development trend of wave and tide coupling simulation,use the continuous storm tide level change process to superimpose the wave process after the encrypted and discrete wave,and through the wave making machine and the tide generating equipment,we make the continuous tide generating wave.In the water trough,the synchronous change of tidal level and wave is realized in the tank,thus the coupling simulation of wave and tide is realized in the laboratory,and it is applied to the simulation example.
