| 摘要： | The breaking wave interactions on a vertical wall with three different recurved parapets were examined in two different scales (1:1 and 1:8) to study the scale effects. A similar testing condition with that of the large scale was adopted to identify a method for scaling up the small-scale laboratory measurements that involve impact pressure or forces. In the present study, two approaches for scaling up the small-scale studies, namely the Froude and Cuomo methods are adopted. By comparing the scaled-up results from small-scale studies with large-scale studies using the two approaches, a combined approach was suggested to estimate the force by integrating the pressure. In the proposed approach (named Cuomo-Froude method), the Cuomo method was adopted in the impact zone, and the Froude method was adopted in the nonimpact region for upscaling the small-scale experiments. The proposed approach shows a reasonable comparison with large results for pulsating and impulsive breaking conditions with a vertical wall having a different exit angle. Finally, the paper concludes that the pressure impulse follows the same scale for wave impacts as pressure. |
