【Abstract】 From studying the distribution of axial force and friction along the DX pile under the vertical load, the developing process through which the load is distributed on expanded bodies and shared by them is analyzed by the numerical simulation of FEM. The characteristics of axial force of different piles are compared. Thus the load transmission mechanism is proved, and the basis for the reasonable of DX pile are provided.更多还原
