The large-diameter cylindrical pile is applied to the vertical pile due to high strength, durability and other economic advantages, but it’s hard for the large-diameter cylindrical pile to bear the horizontal load, so it is considered to adopt the steel pipe pile to bear it, which is reasonable in design idea and arrangement, feasible in construction, and can adapt to the development demand of wharf enlargement and specialness. The successful application of φ1 400 large-diameter pile and cylindrical pile in Lianyungang may serve as reference for the pile foundation design of similar projects in the region.
