摘要：
In this study, we performed experiments in a two-dimensional glass wave flume in the water resources laboratory at Guangxi University to investigate the dynamic pressure distribution characteristics of seawalls under regular wave impact. We then established a physical model of a stepped seawall structure with different structure parameters. By comparing the distribution of the dynamic pressure characteristics resulting from the wave impacts on the horizontal and vertical steps of a seawall, we analyzed the correlation between the dynamic pressure, the seawall slope, and height of the seawall step after the seawall had been impacted by sea waves. The study results show that, within a certain range of seawall slope, and under the same incidence conditions, if the height of seawall step is fixed, the lower the rate of change of seawall slope, the larger the dynamic pressure on the surface of the seawall. © 2016, Editorial Department of Journal of HEU.
