Three-dimensional model test in wave basin is set up combined with the project of Haifeng power plant terminal. The design wave parameters for the breakwater, wharf structure and revetments are obtained in the wave basin. Also, the overtopping on wharf surface and the distribution of wave heights are studied in the experiment. Based on the test, the wave heights distribution in different layout schemes are analyzed to determine the optimal scheme and provide a scientific basis for the design and construction of the harbor. Meanwhile, the effect of excavation of navigation channel and construction of breakwater on wave transmission is briefly discussed.
