| Abstract: | Based upon the working principle of prestressed reinforced concrete(PRC), as well as the loading and deformation mechanism of circular section cantilever retaining piles, the section character, the strength and the details of the pile are discussed. The formulas of reinforcements are derived and the appropriate angle of reinforcements and the relation between the ultimate bending strength with the diameter of the pile are given. The conclusion that the circular PRC cantilever retaining pile can save steel and control deformation is drawn through an example. |
