【 摘 要 】

In recent years, more and more seawalls have been used in tidal areas along coastal areas. The frame type seawall has the advantages of no water occupation, land saving and light weight. It is a difficult problem to determine the overtopping and the elevation of the embankment. In this paper, a physical model test was carried out to measure the average overtopping of a framed seawall at the design frequency of wave height, and the average overtopping was calculated by using the theoretical formula. The results of physical model test and theoretical calculation were compared and analyzed. The results showed that the theoretical formula was 6 to 20% larger than that of the physical model test. Finally, the theoretical formula was proposed to predict the wave overtopping of frame seawall, which met the design requirements and provided a basis for determining the height of the top of the seawall. At the same time, the physical model test showed that the anti-arc cantilever wave absorber on the upstream side of the frame seawall can reduce the overtopping volume by 7%-32%.
