Abstract: The design of the prestressed concrete tubular pile foundation about the deep thick soft soil with the low shear strength in the corrosive environment in the coastal areas was introduced through an engineering example, wluch discusses from the aspects of the negative frictional resistance, the pile foundation durability enhance and the construction measures.
Keywords: PHC pile; negative friction; corrosive; durability; pile foundation protection; deep soft soil
