| description | Landslide-induced tsunamis are common natural hazards that potentially affect the safety and stability of waterfront structures. A numerical tank was constructed using FLOW-3D to investigate the hydrodynamic response of the sea-wall subjected to artificial submarine landslide-induced tsunamis, including the hydrodynamic load and wave run-up height. Initially, the landslide-induced tsunami model was calibrated using experiments to ensure high accuracy for capturing the free surface and obtaining the flow field information. Then, the sea-wall was added into the numerical tank to study the hydrodynamic response of the sea-wall. The results show that the artificial landslide successively generated two wave crests and that the hydrodynamic response of the sea-wall under the second crest was stronger than that under the first crest. Additionally, the effects of different influencing factors on the hydrodynamic response were discussed, respectively, and prediction equations for the hydrodynamic response considering these factors were proposed. |
