Research on wave physical model for Taiping bay of Dalian Port

The wave conditions in the harbor area and the overtopping of the wharf for preliminary project of Taiping bay were determined through 3D wave physical model test, and the optimal layout was suggested based on the test results. The results show that, in the design scheme under the action of W wave direction, wave gets through the approach channel slope into inner harbor, and it reflects back and forth on front of the wharf, so the wave height is bigger. In the design scheme under the action of WSW wave direction, the refraction is more obvious than W direction, but the multiple reflection of waves in the inner harbor is basically the same as W direction. And wave height decreases because of the excavation of channel slope enhance the refraction of waves in optimization scheme one. The optimization case two, in which the north side of the breakwater is extended to 874 m, is better than the optimization case one. While in the optimization case three based on optimization case one, the wharf type is changed into high-pile wharf at the outer end of the east wharf for 1 km. The wave dissipation effect is slightly obvious under low water, but the wave transmission effect has not been fully developed in high water level.
