In order to find out the mechanism of tsunami soliton on bridge girder, the soliton experiment was carried out with a bridge girder model. As a result, the measured maximum horizontal force on bridge girder by force transducer was found close to the calculated maximum force by the integration from the wave pressures on girder side area and the maximum forces happened at the same time. Thus, it is concluded that the horizontal force is dominant to the wave pressure on girder side area. Besides, from the parametric study of wave height, it is noted that both horizontal force and wave velocity are proportional to wave height. Thus, it is concluded that bore wave horizontal force has a high correlation with wave height.
