Abstract:
Failure mode of single pile was derived based on the mechanical behavior of tapered pile. On the basis of the Coulomb's earth pressure theory, a new calculating method of bearing capacity of tapered pile under this failure mode was developed by utilizing limit equilibrium theory. Then, through the comparison of numerical analysis results with results obtainded by using self-made program, the rationality of this method was proved. It shows that the ultimate bearing capacity of tapered pile increases significantly with the increase of cone angle within a certain extent. Rough pile side is also used to increase the bearing capacity of tapered pile when the external friction angle is larger correspondingly. The size of tapered pile has important influence on the bearing capacity. It seems that this new method has good feasibility in engineering practice.
