The Yushan Green Petrochemical Base has formed the land area through the large-scale reclamation. Compared with the original natural reef terrain，the boundary conditions such as wave，tidal current，and bottom topography in the harbor area have changed after reclamation. To reasonably design the wharf structure and meet the normal use after completion，we analyze the design conditions including ship type，cargo type，use load，wave，tidal current，seabed scouring and silting，port construction status，and marine environment corrosion，and solve the key problems including the selection of position and azimuth of wharf apron，selection of hydraulic structure and assurance measures of structural durability in Yushan Phase I project. The results show that the wharf structure is safe and reliable and in good use since it is fully completed and put into operation in 2019.Various structural design parameters have been well verified. The construction of Yushan Phase I project plays a huge economic benefit and social benefit.
