Aiming at the water area layout of the large bulk cargo jetty in complex water area,based on the coal unloading jetty of coal-fired emergency power station in Qasim Port,we put forward preliminary general layout according to the in-depth analysis of the main influence factors,such as the surrounding built projects,mangroves and hydrodynamic condition etc,optimize the layout and relevant dimensions by the ship handling simulation test,and reasonably determine the water area layout of the proposed jetty.The results show that the construction of the project has little impact on the surrounding area,the scale of the water area can satisfy the requirements of ship navigation,berthing and unberthing in it.The layout of water area is reasonable.
