In this paper, the situation of wave over-wavelength changes on stepped dikes is studied experimentally. In the experiment, a wave condition of 25 cm and a wave period of 0.5 sec, 0.6 sec, 0.7 sec, 0.8 sec, 0.9 sec, 1.0 sec, 1.1 sec, 1.2 sec, 1.3 sec, 1.4 sec, and 1.5 sec was used and placed. A stepped levee, a sloping embankment, and a composite stepped levee with a height of 9 mm, 12 mm, 15 mm, and a distance of 1 cm, 2 cm, 3 cm, 4 cm, and 5 cm are combined to record the wave change and the wave amount. The results of the experiment show that the slope type of embankment is the largest, and the slope embankment is like a platform. The waves come to the slope embankment instead, because the slope goes up, causing a larger wave. The wave energy dissipation effect of the stepped embankment and the composite stepped embankment is different. In the case of different height and distance, some of the steps are better, and some conditions are better for the composite stepped embankment; In the future, for coastal construction methods, for shallower coasts, stepped dikes may be considered for construction, and for deeper shores, composite stepped embankments may be used. Using different coastal construction methods, we can have a better ocean view, better coastal protection, and a better hydrophilic environment. With the study of the gradient wave of the stepped embankment, we hope to provide the future. References for coastal dikes and reference for subsequent research. |
