Abstract Based on the new pile-plate bridge structure project of the coastal national highway in Fujian Province, the hydrodynamic experiments of the pile-plate bridge structure under the impact of plunging waves arewere conducted in the wave flume, . the The wave climbing height and the wave forces of the pile-plate bridge structure under the impact of three stages of plunging waves are were investigated, and compared to those under the impact of regular waves. The influence laws of the incident wave height, wave period, and depth of the water on the wave climbing height and the wave force are were analyzed. The results show that the hydrodynamic characteristics of the new pile-plate bridge structures impacted by the three stages of plunging waves are significantly different, there will beis evident wave climbing phenomenon in the about breaking and breaking stages, and the wave surface elevation after the climb of the plunging wave in the about breaking stage attains 1.99 times of the regular wave; the horizontal wave force of the plunging wave at the about breaking stage is the strongest, which is 4.48 times of the amplitude of the vertical wave force in the same stage, and can be 3.08 times of the horizontal wave force of the regular wave. The wave parameters and water depth significantly influence the hydrodynamic characteristics in three stages of plunging waves. With tThe increase of the incident wave height and water depth causes ,the wave surface elevation and vertical wave force in the breaking stage exceed other stages. The increase of wave period makes the wave surface elevation in the complete breaking stage and the vertical wave force in the about breaking stage exceed those in the breaking stage.
