Taking Yangshan deepwater port steel-pipe piled wharf engineering for example,this paper probes into the construction difficulties of rock-socketed piles in the coastal area of complicated geologic conditions,i.e.,setting up of the offshore construction platform, punching and lifting and steel pile welding,and puts forward countermeasures to provide a safe,reliable,convenient and energy-saving construction method for the construction of the rock-socketed pile in the coastal area with complicated geologic conditions.
