For construction of dry docks with other buildings already built around it,a new type of docking wall structure with raking pile platform was researched in this paper for the protection of adjacent buildings.Taking a practical project as an example,PLAXIS software is used to simulate the numerical model of the structure.Key factors such as platform size and slope of raking piles are considered while researching the stress of the dock wall structure.These researches prove that the raking pile platform is availability for protection of adjacent buildings.
