Three-dimensional model test in wave basin is set up combined with the project of all-purpose wharf in Jinghai district of Jieyang harbor. The design wave parameters for the wharf structure and the revetments are obtained in 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 is analyzed to determine the optimal scheme and provides a scientific basic for the design and construction of the harbor. Meanwhile, the effect of excavation of navigation channel and harbor basin on wave transmission and wave conditions in harbor is briefly discussed.
