Abstract
Based on numerical simulation, bearing capacity and settlement control for DX piles are studied. The property differences of conventional straight piles, DX piles with 2 bells and DX piles with 3 bells are presented in condition of identical length, diameter, and bearing capacity. Under the same load, DX piles with 3 bells have smaller settlement than that of DX piles with 2 bells and straight piles. As to bearing capacity, DX piles with 2 bells are 1.5 times greater than that of the straight piles, while DX piles with 3 bells are 1.2 times greater than that of DX piles with 2 bells. The paper can provide theoretical references for the design of bearing capacity of DX piles during the engineering practice．
