Abstract: The pile foundation of the buildings in the reclaimed land area should not only provide the compressive bearing capacity required by the superstructure, but also provide the uplift bearing capacity to mitigate the buoyancy induced from the seawater when the sea water level rises. Therefore, it is necessary to predict, analyze and optimize the layout of the piles in the foundation project, to coordinate the resistance of the pile foundation, the superstructure and the buoyancy from the anticipated sea level. A pile foundation project in Shenzhen Shekou cruise wharf center is presented as the case history. The pile foundation for the buildings in the reclaimed land area is optimized by adjusting the layout direction of the piles under the column, by adjusting the pile position at the edge of the foundation, also by considering the layout of the superstructure. The simulation analysis is performed by using the MIDAS/GTS finite element software to verify the rationality of the optimization design scheme of the pile foundation project.
